Aliens: Colonial Marines was a 12-issue limited comic book series published by Dark Horse Comics irregularly from January 1993-July 1994 set in the fictional Aliens universe.

The series was written by Chris Warner, Paul Guinan, Kelley Puckett and Dan Jolley; drawn by Tony Akins, Guinan, Allen Nunis and John Nadeau; and inked by Guinan, Ande Parks, Terry Pallot, Bob Smith, Jim McDermott and Jordi Ensign. It was lettered by Clem Robins, and colored by Matt Hollingsworth, Pamela Rambo and Doug Jones . It was edited by Dan Thorsland and Randy Stradley and the series featured painted covers by artists Robert Mentor and Joe Phillips (two of the covers focusing on Private Carmen Vazquez).

Colonial Marines was collected and reprinted for the first time in December 2007's Aliens Omnibus, Volume 2.

The Colonial Marines story takes place after the Alien infestation of Earth, the events aboard the Innominata and the destruction of Charon Station. It focuses on a rag-tag unit of Marines investigating Alien-related activities in a backwater sector of space and coming across a mysterious group of Human-Alien hybrids loosely referred to as the "Bug-Men." The series also featured the appearance of the first relative of a character from the Aliens film series with Carmen Vasquez, younger sister of the eminently popular character of J. Vasquez from the film Aliens.
