The Chaser's War on Everything is an AFI winning Australian television comedy series broadcast on the Australian Broadcasting Corporation (ABC) television station ABC1. The series is produced by the Australian satirical group, The Chaser, consisting of Chris Taylor, Julian Morrow, Craig Reucassel, Andrew Hansen, and Chas Licciardello. Fellow Chaser members Dominic Knight and Charles Firth are not part of the regular on-screen cast. However, Knight is a writer, and Firth compiled roving reports for the show from the United States, until he left the group to start a satirical newspaper in mid-2007.

The show premiered on 17 February 2006 and has since produced 50 episodes, broadcast over two seasons between 2006 and 2007. The 2006 season was broadcast at an unstable late timeslot on Friday nights. The 2007 season was broadcast in a more favourable timeslot of Wednesdays at for all 24 episodes. The show will not return in the first half of 2008, and The Chaser are yet to announce if a third season will be made.

The program has often attracted controversy for The Chaser because of the stunts displayed on the show. On 14 July 2006, Licciardello was charged after a stunt concerning rugby league team the Bulldogs. Licciardello was again arrested, alongside Morrow and nine crew members, on 6 September 2007 after breaching security at the 2007 APEC summit.

George W. Bush waged a war on terror, but only The Chaser has had the vision and courage to wage a War On Everything.
