30 Best Episodes Of Star Trek: Voyager According To IMDb

The third spin-off for the franchise, "Star Trek: Voyager" launched not long after "The Next Generation" left the airwaves. Set aboard the U.S.S. Voyager, its first mission saw Captain Kathryn Janeway in pursuit of a group of renegade Maquis. But when both ships were hurled into the far off Delta Quadrant by a mysterious alien entity, the two crews were forced to join together as they embarked on their long journey back to Earth.

Airing for seven seasons on UPN, "Star Trek: Voyager" may not have been the ratings hit that "Star Trek: The Next Generation" was, but thanks to years of reruns and streaming, its popularity has grown in the years since its conclusion, with many episodes ranking among the franchise's most watched, according to StarTrek.com. During its time on Netflix, in fact, episodes centered on the Borg, and fan-favorite character Seven of Nine proved especially popular — so much so that Paramount+ made sure to include both in the revival series "Star Trek: Picard."

But which "Voyager" episodes rank the best among its entire 172-episode run? According to IMDb, the 30 we've collected here are the ones that top the charts.

Janeway is pushed to the brink and Seven is left to save the day in the Season 4 episode "Scientific Method." As the episode begins, the newest addition to the Voyager crew — ex-Borg Seven of Nine — is still learning to adjust to life aboard a Federation starship, unused to the hierarchy of command and the little social niceties of life in a human social structure. 

But while Voyager explores an unusual binary pulsar, a race of cloaked aliens have infiltrated the ship without anyone even realizing it. These aliens aren't looking to conquer however, and instead have been secretly experimenting on members of the crew — including the captain — as a gruesome form of medical testing without their knowledge. With only The Doctor and Seven of Nine able to detect them, it's up to a hologram and an uncertain former Borg to expose the alien threat and save the ship. 

In "Worst Case Scenario" B'Ellana discovers an apparent holo-novel that reanacts a disturbing takeover of the ship by its Maquis crewmembers, led by first officer Chakotay. More intrigued than disturbed, she shares it with Paris, then Kim, and before long the narrative becomes the center of ship-wide gossip as officers rush to play the interactive program for themselves. But it's soon revealed that the story was crafted by Tuvok as a training exercise and was abandoned when the Maquis became valued members of the crew.

Sent back in to finish the story for their own amusement, Paris and Tuvok discover that the program was co-opted by former Maquis crew member Seska and turned into a deadly form of payback. Suddenly the pair find themselves in a cat-and-mouse game with Seska's elaborate scenario that's been designed to torture them, while Janeway attempts to help them outside the confines of the holodeck. Racing against time, they'll have to play by Seska's rules if they want to stay alive.

In the fourth season finale "Hope And Fear," Seven of Nine is forced to confront her humanity when it looks like Voyager has found a way home. It starts with the arrival of a man named Arturis who helps them finally repair and descramble the damaged message they received from Starfleet in "Hunters." In the message, Admiral Hayes claims they've sent an experimental new starship out to meet them just light years away, with a new slipstream engine capable of getting them home in a matter of months.

As Seven of Nine weighs staying behind — unsure if she'll fit in back on Earth — the crew discovers that the ship, the U.S.S. Dauntless, may not be what it appears. Now, the captain must balance her desire to get her crew back to Earth with her feeling that their ticket home may be a little too convenient.

We're seeing double in "Life Line" when The Doctor comes face-to-face with his creator, Dr. Lewis Zimmerman. After his appearance in the "Deep Space Nine" episode "Doctor Bashir, I Presume," the famed scientist is diagnosed with a terminal illness, and Voyager selflessly sends their holographic Doctor back to Earth via the Hirogen communication array to make a house call. But meeting his proverbial father isn't the jubilant family reunion that he'd expected as Zimmerman wants nothing to do with his own creation.

As The Doctor works to push past his creator's stubborn streak, Reg Barclay calls on the services of Counselor Deanna Troi to help the two work through their issues. But a problem in The Doctor's matrix forces Zimmerman to step in to save him, and The Doctor finally learns the basis for his father's ill feelings. A memorable episode that featured two long time cast members from "The Next Generation," it was ultimately a tale of an estranged father and son struggling to find common ground.

In "One," Seven of Nine is attempting to learn social skills with the help of The Doctor — and struggling with it — when the ship encounters an unusual nebula too vast to go around. But the nebula is found to contain a kind of subnucleonic radiation that proves deadly to the crew, save Seven of Nine and The Doctor. The only solution appears to be to put the entire crew, including the captain, into stasis pods for the duration of the journey, while Seven and The Doctor guide the ship.

Left alone, Seven at first enjoys the solitude, but the isolation soon begins to wear on her. Just as she needs companionship the most, The Doctor's program goes offline, and Seven is left to fend for herself as her mind begins to slowly erode. As hallucinations start to confuse her, she'll have to make a fateful choice if she wants to keep the crew alive.

"Someone To Watch Over Me" sees The Doctor once again trying to help Seven of Nine improve her social skills, this time teaching her the art of dating. When Paris finds out, he makes a wager with The Doctor on whether Seven will be able to successfully find a date for an upcoming diplomatic reception. But as The Doctor spends more time with Seven of Nine, he finds himself developing romantic feelings for her himself.

Ultimately The Doctor asks Seven to the event, and when it comes out that he had made a bet with Paris over her love life, things go predictably wrong. Meanwhile, Neelix is tasked with entertaining Tomin, a Kadi diplomat, and struggles to stop the conservative, monk-like visitor from dangerously overindulging in the ship's leisure facilities. A more light-hearted affair, the episode is another key step in the development of both Seven of Nine and The Doctor and their common goal to learn to become more human.

It's double trouble in Season 2's "Deadlock" after Voyager encounters subspace turbulence that seems to be the cause of problems throughout the ship, as the warp core is rapidly being drained. But when B'Ellanna uses a series of proton bursts to restart the anti-matter reaction, it makes things worse, and Ensign Wildman's impending childbirth in sickbay is endangered. After a catastrophic hull break kills Ensign Kim, B'Ellana discovers that the subspace field they passed through has actually created a quantum duplicate of the ship and its crew, and there are now two U.S.S. Voyagers, slightly out of phase but sharing the same anti-matter reserves. 

Unfortunately, just as they think they have figured a way out of the situation they come under attack from the organ-stealing Vidiians. Thanks to the discovery of a small rift that allows passage between the two Voyagers, the duplicate crews find a new way to work together to fend off the alien attack while severing the link between their two ships. But for one of them to survive, the other may have to make the ultimate sacrifice. 

It's an all-out war with Captain Ransom in the sixth season premiere, "Equinox, Part II." After the renegade Starfleet commander reprograms The Doctor and takes Seven of Nine hostage, he sets off to parts unknown to continue his torture of the alien creatures he needs to power his ship. Back on Voyager, Janeway is determined to get back her crewmen — and to do it she threatens to cross the line between justice and revenge. 

With members of the Equinox left aboard the ship, the captain will do whatever it takes to get them to tell her Ransom's plans. While Ransom's EMH secretly attempts to sabotage Voyager, an unexpected ally surfaces and could be key to stopping the Equinox. But as Janeway's methods continue to become more vicious, first officer Chakotay becomes increasingly uneasy, leading to a confrontation that could change the nature of their relationship forever. 

Early in "Star Trek: Voyager" the crew was still hopeful of finding a shortcut back to Earth, and they almost find one in the first season installment, "Eye of the Needle." Encountering a micro wormhole, they realize they can't get the ship through, but may be able to transmit a message, and potentially use their transporters to send the crew back to the Alpha Quadrant. Unfortunately, the ship they find on the other side of the galactic gateway isn't a friendly Federation starship but a secretive Romulan cargo ship.

Attempting to convince the Romulan captain that they aren't some kind of Starfleet deception is the first hurdle they encounter, as the adversaries have little reason to trust one another. But once they finally earn the captain's confidence they discover that the wormhole isn't all that it seems to be. With hopes diminishing, they realize that getting home may be more complicated than activating their transporters.

Season 3's "Future's End" is another classic "Star Trek" time travel adventure that sees the crew of the starship Voyager hurled back in time to the then-present day of 1996. It all happens when the Timeship Aeon emerges from the 29th century and its captain, a man called Braxton, claims that Voyager is responsible for a disaster in his time that will annihilate Earth's solar system. His attempts to destroy Voyager fail, and the two ships are instead sent through a spatial rift, nearly 400 years into the past. 

Arriving in 1990s Los Angeles, Janeway is disturbed to discover that Braxton has been trapped there for 30 years already, and the technology aboard his ship has fallen into the hands of a Steve Jobs-like industrialist named Henry Starling (Ed Begley, Jr.) who is using it to amass his fortune. Realizing that it was future technology that was responsible for the '90s tech-boom, Janeway must find a way to retrieve Braxton's ship and get back to the 24th century, all while Starling hopes to collect Voyager's technology for himself.

Still trapped in 1996, "Future's End: Part 2" sees tech mogul Henry Starling finally getting Braxton's ship operational. Janeway realizes that it's Starling's use of the Aeon that will destroy the solar system, and must find a way to stop him. But Starling manages to steal The Doctor's program, and using 29th century tech taken from Braxton outfits him with an autonomous holo-emitter, allowing him the freedom to walk about unfettered for the first time.  

To get The Doctor back, Paris and Tuvok find a friend in a young astronomer named Rain Robinson (guest star Sarah Silverman), while Janeway makes contact with Captain Braxton himself, now a vagrant living in the city's underbelly. Chakotay and B'Elanna try to locate Braxton's ship, but become prisoner's of right-wing militants. To save Earth and return to the 24th century, Voyager's crew may have to risk exposing themselves to the people of the past.

Another sci-fi time-bender, the Season 7 episode "Shattered" sees the ship pass through a temporal distortion field that fractures the ship into different time periods. Awakening in sickbay more than four years in the past, Chakotay is given a newly developed chroniton serum by The Doctor that allows him to pass through the various time shifts aboard the ship. To bring Voyager back into temporal sync he'll need to spread the serum throughout the ship's own circuitry, but he can't do it alone.

Traveling to the bridge, he finds a version of Captain Janeway from before they met, and he must somehow gain her trust to recruit her to execute his plan. But it's easier said than done with they discover the villainous Seska and her Kazon allies are in control of engineering, during the events of the Season 2 episode "Basics." A nostalgic look back at Voyager's seven-season run, "Shattered" sees the return of several former heroes and villains from past episodes.

The immortal all-powerful trickster Q finds a new ship to annoy in the Season 3 episode "Death Wish." Coming upon a rogue comet, Voyager discovers that it's actually home to a member of the Q Continuum, a being who has grown bored with his endless life and wishes to commit suicide. Dubbed "Quinn," he seeks asylum aboard Voyager when Q arrives to put him back in his cosmic prison cell. Though Janeway doesn't want to get involved in their god-like squabbles, she feels ethically obligated to consider Quinn's request, and grants them a hearing aboard the ship.

While Q summons the likes of Commander Riker, Isaac Newton, and a hippie from Woodstock to give statements, Tuvok defends Q's right to not exist, should he so choose. Disturbed by the fact that granting asylum would mean Quinn's suicide, Janeway attempts to convince Quinn that life is worth living. Undergoing his own crisis of faith, Q is forced to acknowledge the problems his people face, and makes a decision that will change the Q Continuum forever.

 "Latent Image" begins with The Doctor finding evidence of a surgical procedure on Ensign Kim that seems to have no explanation. What starts out as an investigation into a minor mystery leads to the disturbing realization that it was he who performed the surgery, but he has no recollection of it. Soon he learns that someone has been tampering with his program, erasing his memory — and perhaps the memories of the entire crew. But with the help of Seven of Nine, he discovers that the problem is even bigger than he feared, and everyone on the ship may be lying to him.

An episode that explores the problems that come with the holographic Doctor's existence as a growing sentient being, the story shows the crew slowly discovering that he has become more than just a program. It's also an intriguing allegory for how society often treats mental illness, and gives actor Robert Picardo some of his best work in his role as the ship's resident artificial surgeon.

Janeway and Voyager are shocked to encounter another Federation vessel in the Delta Quadrant in "Equinox," the dramatic fifth season finale. Commanded by the revered Captain Ransom (guest star John Savage), the U.S.S. Equinox is a science vessel that was catapulted to the region by the same entity that sent Voyager there. Ill-equipped for deep space assignments, Ransom and his crew have barely been able to survive on their slow journey home, and both crews seem buoyed and hopeful by the chance meeting. 

But the happy reunion is cut short when Seven of Nine uncovers evidence of corruption aboard Equinox, and the discovery that Ransom has been capturing and killing alien creatures and using their corpses to fuel their warp drive. Furious at the violation of Federation ideals, Janeway attempts to take control of his ship. But unwilling to go quietly, Ransom kidnaps Seven of Nine, and along with The Doctor's program, escapes aboard the Equinox. 

In a surprising episode set almost entirely off of Voyager, "Pathfinder" follows "TNG" standout Reginald Barclay as he seeks help from his old friend, Counselor Troi. Now working at Starfleet HQ, he's part of the Pathfinder Project, which hopes to find a way to communicate with Voyager in the Delta Quadrant. Certain that he can use an itinerant pulsar to open a fissure that would allow two-way communication, he uses holodeck simulations to test his theories. But Barclay hit a wall when his superiors didn't believe in the potential of his ideas. 

After his boss, Commander Harkins, discovered that Barclay was living inside a simulation of Voyager and grows concerned for his mental stability, he was kicked off the project. Barclay approached Admiral Paris — who was running the project — about a second chance, but didn't get the response he was looking for. After speaking to Troi, Barclay breaks into the lab to put his plan into action before the pulsar moves out of range.

Janeway comes up with a bold scheme to attack a Borg ship in the double length episode "Dark Frontier," that saw the Borg Queen's debut on the series. The plan is to steal a Borg ship's transwarp technology, capable of getting them back to Earth much faster than their conventional engines, and Janeway will stop at nothing to succeed. But the presence of Seven of Nine on the mission causes her some concern. 

Because Seven of Nine is still adjusting to being fully human Janeway fears the experience of returning to the Borg could be traumatic for her. Unbeknownst to Voyager, though, the Borg Queen has already learned of their daring plan, and finds a way of secretly communicating with Seven of Nine. The Queen offers her former drone a tempting deal: She will allow Voyager to succeed, effectively handing them an easy way home, in exchange for Seven of Nine rejoining the Borg. 

The epic feature length series finale "Endgame" opens in the future on Earth, with an older Admiral Janeway unhappy with how history has turned out. She did get Voyager home, but it took more than 20 years and cost them the lives of several crewmen, including Seven of Nine. But when she finds a way to travel back in time to visit her past self, she devises a plan to change history and get Voyager home much sooner.

Visited by the older, more cynical Admiral Janeway, Voyager's Captain Janeway finds her future self's story hard to believe, but the plan she proposes makes sense: sneak into the heart of a Borg Uni-complex and use one of their transwarp hubs to travel back to Earth in an instant. The plan hits a snag, however, when the younger Janeway instead wants to use the opportunity to deal the Borg a crippling blow. Now the two Janeways find themselves at odds over the choice between defeating a mortal enemy or getting Voyager home.

A story that explores the battle between religious dogma and scientific discovery, "Distant Origin" is told from the surprising perspective of an alien culture. We first meet a pair of Voth scientists named Gegen and Veer, who discover the remnants of one of Voyager's earlier ill-fated away missions. Studying the remains of a human crew member, they match its genetic structure to their own, providing evidence for a theory that their people originally evolved on Earth millions of years ago.

The two scientists show their evidence to their leaders, but are ostracized for challenging long-held doctrine that the Voth are a supreme form of life. Now facing persecution for their scientific discovery, they finally track Voyager itself, and capture Chakotay. With his help they hope to convince their people that they are actually descended from intelligent dinosaurs that roamed the Earth before the first ice age.

A transporter accident fuses Borg nano-probes from Seven of Nine with the 29th century technology of The Doctor's mobile emitter in the fifth season episode "Drone."  Using the emitter, the nanoprobes steal genetic material from a passing crew member to create an advanced, 29th century Borg drone unlike anything that had been seen before. Unconnected from the Borg hive mind, the newly born Borg — who takes the name One — is a blank slate, and Janeway wants Seven of Nine to be his teacher and guide to humanity.

But when the Borg Collective discovers his existence they come to assimilate him, putting the ship, crew, and entire galaxy in jeopardy as they fear the Borg getting access to even more advanced technology. As the drone begins to question her about the Borg, Janeway fears he may want to join them, forcing Seven of Nine to finally answer the question of where she belongs.

A mind-bending time travel adventure, "Relativity" opens aboard Voyager before its first mission when Captain Janeway is touring the ship in spacedock. But somehow Seven of Nine is present, and is secretly searching for a dangerous weapon at the direction of Captain Braxton. But before she can locate it she's discovered, and Braxton pulls her out of time, killing her. Flashing back to the present, a series of space-time fractures are causing temporal paradoxes all over Voyager when they discover a highly volatile temporal disrupter hidden in a bulkhead.

Just before it destroys the ship, Braxton's men abduct Seven again and send her back to find the disrupter in the past, figure out who planted it, and why. But if she's going to save the ship, Seven may have to do the one thing she's been ordered not to: tell Captain Janeway in the past about their future and recruit her to help complete Braxton's mission. 

When The Doctor starts experimenting with a daydreaming program in "Tinker Tenor Doctor Spy" things go wrong, and he finds himself unable to distinguish between reality and fantasy. But when a low-ranking alien agent unwittingly taps into his daydreams, he believes The Doctor is actually the captain of the ship, and devises a plan to invade and conquer Voyager. 

After the bumbling alien spy realizes that he's gotten things wrong, he tries to call off the attack but it's too late to convince his superiors. As The Doctor's fantasy's are spinning out of control, the alien makes contact in the hopes of averting an embarrassing incident. To avoid confrontation, The Doctor must convince Janeway to let him take command. A more playful episode, it successfully mixes the kind of light-hearted comedy that works well with The Doctor, with the best adventure elements the show has to offer. 

"Year Of Hell, Part II" picks up two months after the events of Part I. Voyager is in ruins and manned by a skeleton crew, while Janeway herself is in rough shape, barely able to survive repeated assaults from the Krenim. Tuvok has lost his sight, and requires Seven as his guide, while much of the ship itself is falling apart. Aboard Annorax's temporal warship, Chakotay and Paris are at odds, with Paris wanting to attempt escape while Chakotay wants to help find a way to use the ship's history-altering power to save Voyager.

Janeway meanwhile is attempting to assemble a loose alliance of friendly ships in the hopes of mounting an attack on Annorax. Seven of Nine successfully develops a new kind of temporal shield that they believe will be able to protect them against the Krenim's weapons. But if their plan doesn't work, it could mean Voyager never existed.

In the closest thing "Voyager" got to a Mirror Universe episode, the fifth season episode "Living Witness" saw The Doctor's program activated by an alien civilization some 700 years in the future. There, two neighboring species have been arguing over who started their centuries-old war, and believe that Voyager may have played a part in sparking it. Now with The Doctor active, one historian believes that he could hold the key to discovering just what happened.

Through the use of a holodeck of sorts we view the historical account of how they believed the crew of Voyager started the war. In the recreation, a tyrannical Captain Janeway brutally attacks the Kyrian people with biogenic weapons developed by The Doctor, wiping out entire populations. Now it's up to The Doctor to set the record straight, and if he can't convince them of what really happened, he may be put on trial for the crimes that Voyager is thought to have committed against their people. 

Controversial comedian Andy Dick makes an unexpected appearance in the Season 4 episode "Message In A Bottle" that also marks Voyager's first communication with Starfleet. Upon discovering a Federation starship on the edges of hailing range of a deep space alien communication array, they fail to make contact, so instead send The Doctor's holographic program. Aboard the experimental U.S.S. Prometheus, The Doctor also finds that the ship has been taken over by Romulans, and its entire crew killed.

But with the help of that ship's own EMH, a dismissive and snarky Mark II, it's up to The Doctor to fight back and retake the ship. Once successful, he manages to get in touch with Starfleet and finally let them know that Voyager is alive and well in the Delta Quadrant. An offbeat episode that once again mixes humor and adventure, the highlight is the impeccable comedic chemistry between the two EMH's played by Robert Picardo and guest star Andy Dick.

Opening on the stunning visual of the starship Voyager buried beneath the surface of a mysterious ice planet in "Timeless," we meet a small group of explorers trying to excavate it. Breaking into the ship we learn that the space-bound archeologists are none other than Chakotay and Harry Kim, 15 years into the future. Finding The Doctor's mobile emitter, they've come back to the site of a disaster that destroyed the ship, with the hopes of changing history.

Flashing back to the "present" we see that Ensign Kim has spearheaded a project to retrofit Voyager with the same slipstream technology they were introduced to in "Hope And Fear." To use it, Chakotay and Kim man a shuttle ahead of the ship, to guide Voyager through the slipstream. But a miscalculation sends Voyager off-course and while the shuttle made it safely to Earth, Voyager was doomed. With the help of Borg technology from Seven of Nine's corpse, an older and remorseful Kim must evade Captain Geordi La Forge and the U.S.S. Challenger if he hopes to succeed in his quest for redemption.

After successfully negotiating an alliance with the Borg in the Season 3 finale, "Scorpion, Part II" kicks off the fourth season with the Borg agreeing to give Voyager safe passage through their vast territory in exchange for their help in defeating an emerging new threat: Species 8472. Chakotay firmly opposes the collaboration, especially when the collective sends a Borg aboard to act as a liaison, a female drone named Seven of Nine. Despite their agreement, Janeway's first officer doesn't believe they can trust their new allies.

But thanks to the neural link that Chakotay has retained from the events of "Unity," he proves to be the key to a plan to stop the Borg should they betray them. And once Species 8472 is dealt with that's exactly what they do, with Seven of Nine attempting to assimilate the ship. Remembered for the introduction of Seven of Nine, the character helped reinvigorate the series, and would go on to become one of the franchise's most beloved characters, returning in 2020 in the spin-off "Star Trek: Picard."

In "Year Of Hell" Voyager encounters the Krenim Imperium, a powerful empire that rules a region of space they are attempting to pass through. But little do they know that the key to the Krenim's power is a man named Annorax (guest star Kurtwood Smith), a scientist who has developed a devastating weapon capable of altering history. Annorax has been using the weapon to alter the past in the hopes of restoring his people's empire to their former glory and resurrect his long-dead wife.

While Janeway and the crew are helpless against the Krenim's weapons, they go on the run, mercilessly attacked by the Imperium wherever they try to hide. But when Annorax continues annihilating entire planets in his quest, his calculations are thrown off by Voyager's anomalous presence and they suddenly find themselves his newest target. With the ship falling apart, and time running out, Janeway may have to abandon Voyager if they are to survive. 

In the third season finale "Scorpion" comes face-to-face with the Borg Collective for the first time after they discover that their territory is too big to go around on their journey home. But when they discover a corridor devoid of Borg ships they at first think it's good news. Until they discover an even bigger threat: a new race of inter-dimensional beings known as Species 8472, who are destroying the Borg, and threaten Voyager as well. 

But when The Doctor develops a biological weapon capable of defeating 8472, Janeway hatches a plan to exploit the conflict between the two warring species. Though the crew is conflicted, Janeway hopes to form an alliance with the Borg, and give them the weapon that could defeat 8472. But will Janeway really help the Federation's greatest enemy defeat the only ones who have ever been able to stop them?

In Season 6's "Blink Of An Eye" Voyager encounters a strange planet where time passes at an increased rate where one second for Voyager is nearly a day on the planet. Approaching to take a closer look, Voyager is pulled into its orbit and trapped there, disrupting the planet's natural energy field, and causing frequent seismic disruptions on the surface. Below, the people who live on the planet are in awe at the shining new star in their night's sky, not realizing that it's Voyager. 

Over the next thousand years, the planet's civilization evolves, while just days pass aboard the ship, and Voyager — which they called "the sky ship" slowly becomes part of their society's mythology. But when a brave astronaut from the planet comes to visit (guest star Daniel Dae Kim), he's suddenly confronted with the reality that his childhood heroes aren't at all what he imagined.
