Mike Kennedy is an American comic book writer who has written several comic books in Dark Horse Comics' Aliens vs. Predator line, specifically several spin-off comics tied into the films Alien vs. Predator and Aliens vs. Predator: Requiem. These comics constituted Dark Horse's only new AVP output between 1999 and 2009, during which time the Aliens, Predator and Alien vs. Predator lines were put on hiatus. As such Kennedy is the only comics writer to have worked on any of the three lines during this period.

An important contribution by Kennedy was the creation in 2004 of "The Big Deletion", an in-universe event which cleared up inconsistencies between the continuity of the existing Aliens and AVP comics lines and certain comments in the 1997 film Alien Resurrection.

Kennedy also has experience with other comics writing including the series Lone Wolf 2001 for Dark Horse. He also works in video game concept development.
