If Star Trek: The Original Series were made in 2026, it would be set in 2326 to 2329.
The short answer
Star Trek: The Original Series premiered in 1966 and is conventionally set 300 years ahead, across 2266 to 2269. Made in 2026 instead, the same reach would put the Enterprise in 2326 to 2329 — a span rather than a year, because the series is dated by its seasons and not by anything it says.
The arithmetic
What year would Star Trek: The Original Series be set in if it were made in 2026?
When it was made
If it were made in 2026
Sources disagree: The dating is a reconstruction, and the sources hedge it differently. Wikipedia writes that the show is set "c. 2266 to 2269", with the hedge; ScreenRant's timeline gives the identical span flat, with none. The official Star Trek site places the series only in "the 23rd century" and names no year at all. This page publishes the conventional span, which is the one every timeline reasons with.

Star Trek: The Original Series, in 6 facts
Wikipedia dates the series to the Milky Way galaxy, "c. 2266 to 2269" — a hedge that does real work, because no episode puts a calendar year on the screen. Source
ScreenRant's franchise timeline files the series under the same span without the hedge, heading the section "23rd century: 2266 to 2269". Source
The official Star Trek site declines to date it at all, saying only that the crew "completes its missions in space in the 23rd century". Source
It premiered on NBC on 8 September 1966 and ended on 3 June 1969, running three seasons and 79 episodes. Source
It was created by Gene Roddenberry, whose opening narration sent the ship "where no man has gone before". Source
The official site and ScreenRant agree on the broadcast years to the digit — 1966 to 1969 — while disagreeing on whether the in-universe years can be stated at all. Source
The point
What the shift reveals
Almost every work on this site was dated by its author. This one was dated by its readers, decades later, and the arithmetic above is built on their homework.
That is worth sitting with, because the reconstruction is not arbitrary. Three seasons became three years; the years were fixed by anchoring the whole to references made elsewhere in the franchise. The result is a span that behaves exactly like an authored setting — it can be recalculated, it shifts as a unit, it lands in 2326 to 2329 — while resting on a consensus rather than a script page. The official site’s refusal to name a year is not an oversight. It is the only position fully supported by the material.
So the honest reading is that 300 years is the distance fandom chose on the show’s behalf, and chose well: far enough that the politics of 1966 could be restaged as anthropology, near enough that the crew still argue like people with jobs. The gap had to be settled before the stories could be sorted. Somebody settled it.
Asked and answered
Questions people ask
- What year is Star Trek set in?
- Conventionally 2266 to 2269, one span of years rather than one year, and 300 years after it premiered. The series never says so itself — see the note beside the arithmetic.
- What year would Star Trek be set in if it were made in 2026?
- 2326 to 2329. The span shifts as a whole: both ends move by the same 300 years the original reached.
- Why is it a range rather than a single year?
- Because the dating is derived from the seasons, not from the script. Three broadcast years were mapped onto three in-universe years, so the setting inherited the shape of the production schedule.
- Which is the more honest source, the hedge or the flat number?
- The hedge. A flat span implies the show settled the question, and it did not. This page publishes the flat span anyway, because it is the one every other timeline builds on, and says why here instead.
