Gang of Four are an English post-punk group from Leeds. Original personnel were singer Jon King, guitarist Andy Gill, bass guitarist Dave Allen and drummer Hugo Burnham. They were fully active from 1977 to 1983, and then re-emerged twice in the 1990s with King and Gill. Between 2004 and 2006 the original line-up was reunited; as of 2013, Gill is the sole original member.

The band plays a stripped-down mix of punk rock, funk and dub, with an emphasis on the social and political ills of society. Gang of Four are widely considered one of the leading bands of the late 1970s/early 1980s post-punk movement. Their later albums (Songs of the Free and Hard) found them softening some of their more jarring qualities, and drifting towards dance-punk and disco. Their debut album, Entertainment!, ranked at Number 483 in Rolling Stone's 500 Greatest Albums of All Time, and is listed by Pitchfork Media as the 8th best album of the 1970s. David Fricke of Rolling Stone described Gang of Four as "probably the best politically motivated band in rock & roll."
