Anti-Flag was an American punk rock band from Pittsburgh, Pennsylvania, United States. The band is well known for its politically charged lyrics and activism, focusing on human rights and various left-wing causes. The line-up includes singer/guitarist Justin Sane and drummer Pat Thetic, who founded the band together; later members are guitarist Chris Head, and singer/bassist Chris Barker (#2) who replaced Jamie "Cock" Towns, who had replaced original bassist Andy Flag in 1997 following his departure one year prior. Anti-Flag is known also for their advocacy of progressive political action groups such as Greenpeace and Amnesty International. The band has declared solidarity with Occupy Wall Street and the Black Lives Matter movement.

The band broke up in 2023 following sexual assault allegations against Sane and their social media accounts being deleted. Various sources close to the band state that the breakup was made exclusively by Sane, with the other band members being unaware of the allegations until after.
