This site has very few ads and costs way more than it makes, and truly, I am just fine with that. But if you DO find it useful and want to throw some thanks my way, who am I to argue? ;-)

This Star Trek viewing guide will assist you through watching the entire franchise, based not on production dates, but on in-universe story order, all the way from the 21st to the 43rd centuries. As it is a viewing guide and not a rigid chronology, some episodes are shifted to keep things as clear and fun as possible. The site is updated regularly to stay current.
There is now a print-friendly version without the graphics as well.
To avoid spoilers, I’ve moved discussion of the thinking behind some less clear-cut decisions to a separate “methodology” page. Opinions and feedback are welcome!

Star Trek essentially begins on this date, when Zefram Cochrane creates faster-than-light travel (“warp drive”) allowing humans to meet extraterrestrial life, the Vulcans, for the first time. We will see this event later in the viewing order, but for now it’s just backstory.
We start with Star Trek: Enterprise (technically just titled Enterprise until season three). While the first in the timeline, this show was actually the sixth Star Trek series made, and includes many fun hints of future events. We mostly follow the release order, but will skip some episodes in Seasons two and four until later in the viewing order. Note episodes 11 and 12 are flipped as well.
We are skipping episode 23 (“Regeneration”) for now, but will return to it later.
In its fourth and final season, Enterprise, under the guidance of a new showrunner, really takes advantage of its ability to foreshadow events in later chronologically-placed stories. Please pay attention to the episode numbers as we skip episodes 18, 19, and 22 for now and watch them later.
Although we will be moving on from Enterprise for now, we will return to watch the skipped episodes and the series finale later. Even so, the two-parter above is near-universally considered a better end-point for this point in the story.
The Earth-Romulan War, which was first mentioned in the original 1960s series, occurs here. Enterprise intended to cover this starting in the fifth season, but was unfortunately cancelled after Season Four. While we don't get to see the conflict on screen, its impact is felt throughout Enterprise and beyond. During the war, Humans, Vulcans, Andorians, and Tellarites form a loosely structured Coalition of Planets which manages to push back the Romulans. This Coalition leads directly to…
…the formation of the United Federation of Planets, the primary political setting of the Star Trek franchise.
From this point on, Star Trek focuses on the Federation, depicting its periods of peace, war, expansion, and decline, which will set the agenda for much of the franchise.
An adaptation of an (actual) ancient African legend, told to a young girl we will meet again later as an adult, this is our first “Short Treks” episode. These mini-episodes are not tied to any specific time or place in the Star Trek franchise and will appear occasionally throughout this list.
There are two main “universes” in the Star Trek franchise: the Kelvin timeline (consisting of three feature films) and the Prime timeline (covering everything else). This year, 2233, is when events occur which split the universe into the Kelvin and Prime timelines. For now, we will stay with the Prime timeline in this viewing order, but keep in mind the Kelvin timeline for later. Note that there is a third universe, the "Mirror" universe, and occasional alternate timelines. However, for simplicity, our visits there will not be separated from the Prime episodes.
The USS Kelvin flies through space, exploring strange new worlds.
Nothing happens.
All is well.
After a quick Short Trek in which we meet a young ensign reporting to his new ship, we reach the very first Star Trek episode produced: The Cage, dating from 1964-65. Rejected by NBC for being "too cerebral," studio owner Lucille Ball convinced the network to give the show another chance at a pilot. While much of The Cage’s footage is reused in a later episode, "The Menagerie," we recommend that you don't skip either one. The character of Captain Pike becomes highly significant shortly, and both episodes offer valuable insights into him and Spock.
Viewing notes: When referring to the original 1960s "Star Trek," this guide uses the abbreviation TOS (The Original Series). TOS is available in two versions: the classic 1960s version and a CGI- enhanced remastered version made from 2006-08. The remastered versions do not alter the stories in any way making the version you choose a matter of personal preference.
We now begin Star Trek: Discovery, which is the seventh Star Trek series produced, but only the second series chronologically. It also is the first series to significantly revamp the visual designs, departing from the previous assumption that the 23rd century looked the same as it did in the original 1960s series. Discovery updates the designs, and we are trusted to accept that they have "always" looked this way, affecting uniforms, ships, alien makeup, and more. The Klingons, in particular, received a dramatic redesign, though it was significantly backtracked after the first season. These are not continuity issues, and should not be viewed as such, though we could certainly nitpick details if we chose to.
Watching Trek in this order presents a quirk in episode 10, where the USS Defiant is, to avoid spoilers, somewhere it shouldn't be. The show assumes that we know the explanation, but don't worry about it. We will learn why when we reach 2268, but in the meantime, it is entirely unimportant to how the story in Discovery unfolds.
I will avoid spoilers, but after watching the episode listed just above, it will be clear why we are pausing our viewing of Discovery, even though there are more episodes left to watch. We will come back to the series at the appropriate time to continue the series.
We now move away from the Discovery crew to follow Capt. Pike, back in command of the Enterprise, for an absolutely delightful series that deliberately throws back to 1960s Trek in many ways, including the first appearances of some characters we will continue to see for many years to come.
Skipping Episode 7 for later…
Pay attention to the possible future laid out in this next episode; we see how the timeline actually plays out later in this chronology.
Here’s that second Original Series pilot Lucille Ball fought for, now with (most) of the classic 1960’s Star Trek crew. Still no Dr. McCoy, Uhura, or Chekov, Kirk has a different middle initial, the uniforms and sets still aren’t quite right… but we are for the first time recognizably in the world of the show that started it all.
Just to clarify - the original Star Trek will appear less advanced in terms of its designs and aesthetic compared to the other Star Trek shows we have watched so far, but this is only due to the limitations of television production at the time. This is not “true” in story terms - the technology and society in TOS should be read as on par with Discovery and Strange New Worlds, which all take place at roughly this point in the timeline, and the Enterprise, despite looking different, should be accepted as the exact same ship Pike commanded in Strange New Worlds.
As for the actual viewing order, to fully appreciate the development of the show, it's recommended to watch TOS in production order instead of by air date. In general, don’t get too hung up on continuity with the rest of the franchise in these early days - they take quite a while to pin some stuff down that the rest of the franchise takes for granted.
The Menagerie is largely reedited from The Cage, which we watched a while back, but don’t skip it - after spending so much time with Spock and Pike since, this episode is absolutely essential.
Next we revisit SNW’s season 1 finale, “A Quality of Mercy”, and see how differently events play out with Kirk in command of the Enterprise.
While Mirror, Mirror is the episode that first introduces the Mirror universe, we’ve already been there on Discovery. Enterprise had a two-part episode there too, actually, but that’s one of the ones we skipped for later viewing and will be arriving at shortly.
In one of the more fun examples of the shows tying together, the next three episodes we watch have a TOS episode leading into two of the Enterprise episodes we skipped, PLUS they finally explain why the Discovery detected the USS Defiant in the Mirror Universe.
We finish Kirk's Five-Year Mission with Star Trek: The Animated Series. Is TAS in continuity? Debatable. In later years, Star Trek creator Gene Roddenberry liked to say it was not, but later works in the franchise certainly seemed to disagree, with Enterprise’s Vulcan arc as well as the first of the Kelvin films borrowing heavily from Yesteryear, Robert April appearing in Strange New Worlds, numerous references in Lower Decks, etc., so I see no reason not to consider it as canon as everything else. Besides, “La mort de l'auteur” means we don’t have to listen to Gene.
Movie time! Some background here. Paramount was planning on making a new network, and intended a new Star Trek series, "Star Trek Phase II", to anchor it. Scripts were written, sets were built, and actors cast. When network plans fell through, and Star Wars became a hit, they decided to take one of those scripts and streeeeeeeeeetch it out into a movie.
So…. Is it way too long for the amount of plot it has? Yes, though it has its charms. And isn’t it basically a retread of Nomad from the episode "The Changeling" anyway? It is. And hey, isn’t that the pedophile Dad from 7th Heaven? mm-hmm. Anyway, if you have access to it I recommend the Director’s Cut, in which pacing is much improved and some particularly flawed effects are redone, but either version works story-wise.
Following The Motion Picture, the franchise underwent a significant transformation with the release of the next film, adopting a different style and tone that many, including the author, believe resulted in the best Star Trek movie to date.
Ephraim and Dot ’s continuity really makes no sense anywhere, but it’s cute so who cares. Anyway, this seemed the BEST place to put it.
Or, to use the all-but-official secondary title, “The One With The Whales”
A criminally underrated film.
Sidenote: The opening sequence of the film. Star Trek: Generations takes place this year, a few months after The Undiscovered Country. I very much do not expect people to watch things in pieces, but as there IS a clear delineation in the film, you can, optionally, watch the beginning of Generations and stop when the “78 years later” caption comes up. Or you can just not worry about it, and watch the whole film in one sitting when we reach 2371.
We now jump forward 70-odd years to see a far more established Federation, and perhaps the most popular and beloved Star Trek series of all, Star Trek - The Next Generation. That said, it is extremely rough at the outset, so you’ll need to give it some time. I promise you, the series gets a lot better later on and absolutely earns the affection it still receives to this day.
This season introduces the most popular and iconic character of the entire Star Trek franchise: Riker’s Beard. More seriously, due to a writers strike this year the producers had to dip into episodes written for the early 70’s Phase II series that was never made. Will Riker and Troi were ALWAYS a revamp of the original plans for Will Decker and Ilia, but the season opener was literally written in the 70s with Ilia in the place of Troi.
The series doesn’t truly find its footing until Season 3, but “The Measure of a Man” is widely considered TNG’s first “great” episode, a sign of many more to come.
We now reach my personal favorite series: Star Trek - Deep Space Nine, which will eventually feature Star Trek’s first significant attempt at serialized storytelling. Like other shows in the franchise, it has a slow start, but once it gets going it’s a real joy. To stay in the correct chronological order, we’ll be bouncing between TNG and DS9, and later DS9 and Voyager, with occasional minor tweaks to avoid interrupting story arcs in progress.
Pay attention to this next episode - it will be important (much, much) later.
By the end of this year we’ll have bid farewell to The Next Generation with the fantastic series finale “All Good Things,” we’ll have finally watched Enterprise’s far less popular finale “These are the Voyages…”, and we will have been introduced to The Dominion, the major story driver for most of Deep Space Nine.
Like Phase II was intended to do, and Discovery does again a few decades later, Star Trek Voyager is launched as the centerpiece of a new network: the short-lived UPN, home of Shasta McNasty and The Secret Diary of Desmond Pfieffer. Note that Voyager episode orders, particularly in season two, jump around a bit due to some production weirdness.
Only took 222 years, but after this next episode, we’ll have completed all of Star Trek Enterprise.
Voyager gets a much needed shot in the arm with the introduction of Seven of Nine, and Deep Space Nine delivers a great season as the Dominion War arc reaches full swing.
We are skipping Voyager episode 23 (“Living Witness”) for now, and will be watching it later.
There’s no place where Insurrection’s references to the Dominion War and the presence of Worf really make perfect sense, but this is probably the closest to working. I’m not going to go too nuts about it.
Farewell, DS9. I’ll always love you best.
Star Trek returns to animation with its ninth series, and first all-out comedy, Star Trek: Lower Decks, aimed towards a more adult audience than The Animated Series or Prodigy.
We now travel back for our last Strange New Worlds episode, which is ABSOLUTELY a delight.
The first Star Trek since The Animated Series to be geared explicitly for kids, Star Trek: Prodigy takes place on the border of the Delta Quadrant last seen in Voyager, and features the return of several characters from that series. Don’t dismiss this as “just a kids show” though — it’s quite complex, quite good, and quite Star Trek.
Keep an eye out this season for mentions of the Romulan supernova and evacuation, and the “Narada Incursion,” all of which you will hear more about shortly in the Kelvin films and in Star Trek: Picard.
We now reach the last episodes of Prodigy. As of this writing, it seems unlikely that there will be a third season, but personally, I sure hope there is — it’s been a great show. In the finale, you will see an incident on Mars that is also explored in the following Short Trek. This event sets much of Star Trek - Picard in motion, so keep it in mind, but before we view Picard we’ll be taking a little sidetrip away from the Prime Universe…
Okay. Deep breath. In 2387 the Romulan sun goes supernova, devastating the Romulan empire. A failed attempt by Starfleet to help stop this accidentally sends the Romulan mining vessel Narada back to 2233, creating an alternate reality known to fans as the “Kelvin Universe” or “Kelvinverse,” and referred to in-universe as the Narada Incursion. We'll be watching the three movies set in this universe next. It's essential to note that this new timeline DOES NOT replace the original “Prime” timeline, which still exists as it always has and to which we will be returning shortly.
The USS Kelvin is destroyed by the Narada, newly arrived from the Prime Universe 2387. This begins the divergence from the Prime timeline.
Too action-oriented for some, and plot-holes galore, 2009’s “Star Trek” is not what I would want Star Trek to be all the time, but is a quite fun alternate take on the original series, with some great acting and effects. Don’t overthink the chronology and details of this batch of movies though, or you’ll start seeing all kinds of things that make no sense.
This film, while a solid improvement on Into Darkness, did not perform to expectations, meaning that the long-promised fourth film has been in-and-out of production for years, and I cannot say if we’ll ever see the Kelvin timeline again.
Therefore, we now return to the Prime timeline, already in progress, fourteen years after the attack on Mars we saw at the end of Prodigy.
We now start Star Trek Picard, which is… um. Season 3 is pretty okay?
I gotta say, I strongly feel the Picard seasons all would make much more sense if you assume A LOT more time takes place between them than what the official sources say, but it is what it is.
As you watch this you’ll see why the exact placement can be debatable, but 3074ish seemed best. With this episode, we finish Star Trek: Voyager. Keep in mind that this episode takes place entirely in the Delta quadrant, far away from most of the events of the franchise.
Several hundred years later, we rejoin Star Trek: Discovery, already in progress, to discover what has happened in the interim.
And with Calypso, we end our journey - FOR NOW - but new episodes that take place earlier in the chronology are still airing, and with luck Star Trek will NEVER truly end! Thank you for joining me on this. I am honored, and I hope you enjoyed it as much as I did!
