Enemy Territory: Quake Wars is a first-person shooter video game developed by Splash Damage and published by Activision for Microsoft Windows, Linux, Mac OS X, PlayStation 3 and Xbox 360. The game was first released in the PAL region on September 28, 2007, and later in North America on October 2. It is a spinoff of the Quake series and the successor to 2003's Wolfenstein: Enemy Territory.

Quake Wars is a prequel set in the same universe as Quake II and Quake 4. New features include the addition of controllable vehicles and aircraft as well as multiple AI deployables, asymmetric teams, much bigger maps and the option of computer-controlled bot opponents. Unlike the previous Enemy Territory games, Quake Wars is a commercial release rather than a free download.

Enemy Territory: Quake Wars received mostly positive reviews upon release, with a more mixed reception for the console versions. Since 2011, the rights to the game have reverted to ZeniMax Media
