The Aliens comic book line was a long-running series of comic books published by Dark Horse Comics, based on the Alien franchise, chiefly the 1986 film
Aliens
. For over 30 years, Dark Horse was essentially the sole publisher of Aliens comics, and the company produced a number of limited series, one-shots and short stories, starting with the comic Aliens: Outbreak (originally titled simply Aliens) in July 1988. Following the purchase of 20th Century Fox by The Walt Disney Company in 2019, the license to produce Alien comics moved to Marvel Comics (along with the
Predator
and
Aliens vs. Predator
lines), thus bringing Dark Horse's involvement with the franchise to an end.
During the time they owned the rights to produce Aliens comics, Dark Horse published a total of 72 different Aliens stories, as well as various collected editions, reprints and non-canon crossover comics that introduce the titular Alien species to other franchises. Of the four Dark Horse comic book lines set in the Alien vs. Predator universe, the Aliens line was by far the most extensive (and the longest-running).
