What is the official sequence of the episodes in the original Star Trek series? I'm interested in the sequence of the story rather than when they were produced or when they aired.

    That's the airing sequence. They are ordered by stardate in various lists, but there are something like 5 episodes that never included a stardate, so they aren't able to be placed in a timeline. – Tango Sep 25 '11 at 14:31
  • @Tango That would explain the Wikipedia/Netflix discrepancy. – CajunLuke Sep 25 '11 at 14:49

    @TangoOversway While looking into the Stardate questions, I found a quote from Roddenberry that Stardates always increased from episode to episode, but they didn't air in production order. That's the only reason they appear to jump around. So production order (which gives those episodes without a Stardate a placement) is probably the closest you'll get in-universe. But that's not the list in this answer. – Izkata Apr 24 '12 at 22:47

    You can see evidence of production order (and to some extent character evolution) in the first few episodes. The uniforms change significantly from the "The Cage" original pilot through "Where No Man Has Gone Before", "Charlie X", "Mudd's Women" (in which Spock is referred to as "Vulcanian" rather than "Vulcan"), and Spock takes at least a couple of episodes to settle into his trademark unemotional style. – Anthony X Aug 4 '14 at 16:07
  • The placement of "Where no man has gone before" is highly questionable, given that it has a largely different crew than the rest of the episodes. I always placed that one between "The Cage" and the rest of the series. – ApproachingDarknessFish Aug 17 '16 at 20:39

There is no "order of the story" for TOS episodes. TOS was not intended to have an 'arc' like DS9 or Enterprise. Hardly any TV series did so at the time. You can pretty much count on one hand the number of times an episode makes reference to a previous episode, and none of them are important to the plot.

Reading the description of the early years of filming it is clear that the order of episodes was changed for all sorts of reasons other than plot. For example the first episode filmed (after the pilots) was The Corbomite Maneuver, chosen because it was almost all shipboard and meant the production staff would be climbing into the shallow end. It aired well into the first season.

Your only options are the airing date order or the stardate order, which generally corresponds to production order.


So the assumption that the stardates coincide with the production order is not entirely correct.

Here is the first season in order of stardate. (however I do prefer to watch in order of production)

Where No Man Has Gone Before    1312.4 - 1313.8
Mudd's Women                    1329.8 - 1330.1
The Corbomite Maneuver          1512.2 - 1514.1
The Man Trap                    1513.1 - 1513.8
Charlie X                       1533.6 - 1535.8
The Enemy Within                1672.1 - 1673.1
The Naked Time                  1704.2 - 1704.4
Balance of Terror               1709.2 - 1709.6
The Squire of Gothos            2124.5 - 2126.3
What Are Little Girls Made Of?  2712.4
Miri                            2713.5 - 2713.3
Dagger of the Mind              2715.1 - 2715.2
The Conscience of the King      2817.6 - 2819.8
The Galileo Seven               2821.5 - 2823.8
Court Martial                   2947.3 - 2950.1
The Menagerie, Part I           3012.4 - 3012.6
The Menagerie, Part II          3013.1 - 3013.2
Shore Leave                     3025.3 - 3025.8
Arena                           3045.6 - 3046.2
The Alternative Factor          3087.6 - 3088.7
Tomorrow is Yesterday           3113.2 - 3114.1
Space Seed                      3141.9 - 3143.3
The Return of the Archons       3156.2 - 3158.7
A Taste of Armageddon           3192.1 - 3193.0
The Devil in the Dark           3196.1
Errand of Mercy                 3198.4 - 3201.7
Operation -- Annihilate!        3287.2 - 3289.8
This Side of Paradise           3417.3 - 3417.7
The City on the Edge of Forever Unknown 

If you go by star date, here is a link to a good list. The series was not run in order by star date, very confusing.

For me, it makes more sense to watch them in production order and ignore any stardate discrepency. Watching the 2nd pilot after 2 normal episodes just seems wrong.

    That is precisely what the question was not asking for. It can make sense to watch them in production order, I agree, but the OP was interested in the official chronological order, which is a different thing. – bitmask Dec 8 '12 at 17:18

    I disagree - the user said they weren't asking for production OR airing order, but "story" order. While there aren't any real story arcs in TOS, watching the episodes in production order basically allows you to see the characters (and nerve pinch, mind meld, etc.) develop in the order they did, and there is the occasional mention of something before it happened if you go by air date, though that's mostly minor. For me, production order is MUCH closer to "story order" than airdate order... – Fred Hamilton Jan 17 '15 at 5:53
  • +1 for last sentence. Airdate order does seem just wrong – philsf Jan 7 '17 at 22:22

Production order is the order I have always found most satisfying, particularly as there were changes to the sets and the costumes in the early episodes, and production order is the only way these are consistent rather than being rolled back then reinstated.

The first full UK video release was in production order, and it is of great frustration to me that the DVD and Blu-ray releases have been in broadcast order.

    OP said "I'm interested in the sequence of the story rather than when they were produced or when they aired." Production date comes much closer to any intended "sequence of the story" than airdate does. – Fred Hamilton Jan 25 '15 at 21:00

Gene wanted the show to appear in the order it was filmed, not the order is was aired. This is why he "invented" the star date story about to explain the shows being out of sequence. I remember I was there. Here it the order Gene Roddenberry wanted them to be seen in, Netflix lists them in the order they appeared on TV which is NOT the correct order.

  1. The Cage (unaired pilot)
  2. Where No Man Has Gone Before
  3. The Corbomite Maneuver
  4. Mudd's Women
  5. The Enemy Within
  6. The Man Trap
  7. The Naked Time

    Do you have a reference for Roddenberry thinking it was important to show episodes in the order they were filed? He was pretty much in charge at the time. Why didn't he do it? – DJClayworth Jan 15 '14 at 19:24
  • You were there when Gene Roddenbery explained the stardate story? I think that's not what you meant to write. – neilfein Dec 29 '14 at 0:51

    The reason the shows were shown out of sequence was largely due to how long it took to do the special effects. Sometimes it was just because the producers hated an episode so much (Alternative Factor) that they put off airing it as long as they can. Reference Cushman's These Are The Voyages books. All things being equal I'm pretty sure they would have wanted the episodes shown in production order, since there was an evolution of characters and background as the series was being made. I feel production order is much closer to what Roddenberry would have wanted vs. airdate. – Fred Hamilton Jan 25 '15 at 20:56

The only REAL way to watch any show from this era which doesn't have a defined arc relating events from previous episodes to later episodes is DEFO Not airdate order, or Stardate order or even production order but the order that the episodes were ACTUALLY FILMED IN as that would maintain the most honest continuity available.

Production order doesn't always represent filmed order.

So wheres a list of FILMING episodes as in production diary?

  • If you found such a list and included it in your answer, that would be a considerable improvement. – Politank-Z Sep 15 '17 at 1:15

In the 2009 CBS remastered DVD edition - 3 season box set, the episodes appear in the release date sequence with the original un-aired Pilot "The Cage" feathered at the end on the 3rd disk, with commentary by Gene. However, on each DVD main menu episodes are identified with a single number. This is separate from the star date and runs out of sequence with the release dates. These numbers correspond to the production sequence listed above and seem to make the most sense in the evolution of characters and the ST universe.


Michael and Denise Okuda, in the official (but not necessarily canonical or accurate) Star Trek Chronology: The History of the Future 1993 give the TOS episodes in production order. so one could say that if you go by the DVD release the airdate order is official for TOS, and if you go by Star Trek Chronology: The History of the Future the production order is official for TOS.

If someone has a list of episodes ranked in order of quality they can watch or show them in quality order starting with the best to get someone to like the series, or start with the worst and work up in quality knowing that the episodes will get better and better.

I guess someone could also plan to watch the episodes in alphabetical or reverse alphabetical order.

As a general rule most Star Trek TV shows can be viewed and/or fictionally happen in at least four different logical orders listed in no particular order:

1) Airdate order.

2) Production order.

3) Stardate order (some episodes don't have stardates, including all Enterprise episodes, and thus need to be placed rather arbitrarily.

4) By order of season, and within each season all episodes with stardates ordered in stardate order, and stardateless episodes placed rather arbitrarily. Since there is some overlapping of stardates between seasons, this allows for the first, second, and third seasons of TOS to correspond with the first, second, and third years of the five year mission, for TAS to be the fourth year, and for TOS novels to be the firth year of the five year mission, a popular fanon.

I hope to write a book about Star trek chronology someday, giving three alternate chronologies for readers to choose from.

In one chronology I will put every episode of TOs, TAS, TNG, DS9, and Voyager in stardate order when they have stardates and in the most logical order when they don't. I have a highly original theory about Next Generation era stardates.

As most of us know, during the second or third season and later seasons of TNG the creators managed to produce and air the episodes so that production order, original syndication airdate order, and stardate order are exactly the same for almost all episodes. thus there will be very few problems with putting the majority of all Star Trek episodes and movies in order according to my theory about Next Generation era stardates.

And I intend to extend the Next Generation era stardate system back to the second and first season of TNG, the TOS movies, and TAS and TOS.

But won't there be problems with that, like for example, tasha Yar being alive in an episode ith a later stardate than the one she was killed in?

No, because I believe that highly episodic TV shows should be thought of as being about the adventures that could happen to the characters and thus that do happen to them in various alternate universes. Thus Tasha Yar can be alive in one universe after being killed in a totally different alternate universe. And thus TOS episodes with stardates too close together or even overlapping can and must happen in alternate universes to each other.

TAS episodes can have stardates overlapping with first, second, and third season episodes because they happen in alternate universes where the Enterprise has different equipment and some different officers than in the live action episodes. Animated episodes that seem like sequels to live action episodes are actually sequels to somewhat similar but not identical series of events happening in alternate universes to those live action episodes.

My second chronology would almost always put the episodes in production order - except in cases like "Unification Part II" being produced before "Unification Part I".

So from the second or third season of TNG on the episodes would be in the same order as in the first chronology. But in the first and possibly second season of TNG and in the TOS movies, TOS, and TAs, the productions will be in production order and a different stardate system will be used to explain how stardates can go up and down and up and down again and to predict and calculate when in Earth time a particular statedate can be found.

my third chronology would be like the second in having the episodes mostly in airdate order which will be mostly identical with production and stardate order for everything after the second or third season of TBG, and will have a different stardate system for everything before, explaining and calculating how they go up and down and up and down again.

What about the way the sets and costumes and characters gradually changed, especially in the first few episodes produced? Since the episodes mostly all happen in alternate universes, they can happen in alternate universes where old style uniforms are replaced by new style uniforms, for example, at different times.

So basically there is no real official order for TOS episodes but production order is probably closest, and I hope to produce three separate chronological systems to make production order, stardate order, and airdate order make equal sense.


Production order has always been my preference and the only "logical" choice. The first US DVD release (40 volumes, 2 episodes per disk) was in production order, but all US DVD releases since have instead been in air date order.

  • But is the production order the sequence of the story? – Null Dec 31 '15 at 5:39
