As a rule, ''Franchise/StarTrek'' makes no effort to maintain continuity outside of its LiveActionTelevision series and films -- in fact, for a while, there was a directive that tie-ins couldn't reference anything except the [[Franchise/TrekVerse live-action canon]]. Novels, comics, video games, roleplaying games, technical manuals etc. draw from their common origins, but exist largely independent of each other save for occasional {{Shout Out}}s or borrowed elements.

There is a modern line of ''Franchise/StarTrek'' novels from Pocket Books which make an effort to be consistent in regards to continuity. Most novels from the year 2000 on are ''generally'' set within the same reality. This continuity is discussed on the Franchise/StarTrekNovelVerse page.

Some of the older books have been retroactively absorbed into the "Novel Verse" continuity, most have not.

There are (naturally) many ''Franchise/StarTrek'' comic books, including:

* ''Star Trek'' (Gold Key series, 1967-1978) -- set during the Original Series
* ''Star Trek'' (Marvel series, 1979-1981) -- set after ''Star Trek: The Motion Picture''
* ''Star Trek'' (DC series, 1984-1996)
** Volume 1 (56 issues, 1984-1988) -- set after ''Star Trek II: The Wrath of Khan'' and around the next two films, with a few issues set during the Original Series or [=ST:TMP=] era
** Volume 2 (80 issues, 1989-1996) -- set after ''Star Trek V: The Final Frontier'', with several issues set during the Original Series
* ''Star Trek The Next Generation'' (DC series, 1988-1996)
* ''Star Trek Deep Space Nine'' (Malibu series, 1993-1996)
* ''Star Trek Deep Space Nine'' (Marvel series, 1996-1998)
* ''ComicBook/StarTrekStarfleetAcademy'' (Marvel series, 1996-1998)
* ''Star Trek: Early Voyages'' (Marvel series, 1996-1998: set during Christopher Pike's command of the ''Enterprise'')

* ''Star Trek Divided We Fall'' (Wildstorm miniseries, 2001)
* ''Star Trek Countdown'' (IDW miniseries, 2009) -- Billed as the "official prequel" to the rebooted ''Star Trek'' film and written by the screenwriters, it initially wasn't clear whether this is merely a part of the Expanded Universe, or canon in its own right. After being questioned on certain (minor) inconsistencies between the comic and the final version of the movie, the screenwriters declared it non-Canon.
* ''Star Trek'' (IDW series 2010-) -- Initially a retelling of Original Series episodes based on the alternate timeline started off by the 2009 film. Has since started telling original stories, and has also crossed back over into the original timeline at points.
* ''Comicbook/StarTrekTheNextGenerationDoctorWhoAssimilation2'' (IDW miniseries, 2012) -- Crossover miniseries with ''Doctor Who''; also part of the [[/index]]Franchise/DoctorWhoExpandedUniverse[[index]]
