XCOM (originally called X-COM) is a science fiction video game franchise featuring an elite international organization tasked with countering alien invasions of Earth. The series began with the strategy video game X-COM: UFO Defense created by Julian Gollop's Mythos Games and MicroProse in 1994. The original lineup by MicroProse included six published and at least two canceled games, as well as two novels. The X-COM series, in particular its original entry, achieved a sizable cult following and has influenced many other video games; including the creation of a number of clones, spiritual successors, and unofficial remakes.

A reboot series was published by 2K Games, beginning with the strategy video game XCOM: Enemy Unknown, developed by Firaxis Games and released in 2012 to critical and commercial success. It was followed by the prequel The Bureau: XCOM Declassified and the sequels XCOM 2 and XCOM: Chimera Squad.
