The Weirdos were an American punk rock band from Los Angeles, California. They formed in 1976 and broke up in 1981, were occasionally active in the 1980s, and recorded new material in the 1990s.

The band was formed by singer John Denney and his brother Dix on guitar; they were the only constant members, though guitarist/bassist Cliff Roman, bassist Dave Trout and drummer Nickey Beat Alexander were relatively long-term Weirdos.

They were originally an art rock band formed in 1976, and were featured in a news article featuring punk rock groups in Time magazine and so the punk label stuck.

They broke up in 1981, but reunited at various times, including to record the 1990 album Condor. A 2004 reunion includes in the band's lineup Circle Jerks bassist Zander Schloss and The Skulls drummer Sean Antillon.
