The Mono Men were an American garage punk band, based in Bellingham, Washington.

Their sound contained elements of grunge (distortion-heavy guitars, sneering vocals), but the Mono Men filtered these through a mimicry of 1960s Washington proto-punk, garage rock bands such as The Sonics.

John Mortensen came from the Dehumanizers and Game for Vultures before joining the Mono Men.

They played shows in Europe, Mexico, Japan, Canada, and the United States.

The band split in 1998, though in 2006, the Mono Men reunited to play a series of concerts called the "Spanish Attack."
