John Butler (born 1 April, 1975 in Torrance, California) is an Australian musician having moved to Australia on 26 January, 1986 with his Australian father and American mother. He is the leader of the John Butler Trio, a jam band that has achieved two platinum records in Australia with Three (2001) and Living (2003). Their 2004 album Sunrise Over Sea debuted at number one on March 15, 2004 and shipped gold in its first week of release.

Butler began his musical career as a busker, before achieving his current fame. His band's first two albums were moderately successful, allowing him to establish a largely word-of-mouth following. Sunrise Over Sea, however, featured the single Zebra (so named because Butler was listening to Led Zeppelin and reggae music at the time he wrote it), which proved a major hit Australia wide.

Butler is known for his striking looks, in particular his dreadlocks. He is also outspoken on his left-wing political views, often making political statements at his performances.

As befits a former busker, Butler is famous for the quality of his live performances and his rapport with his audience.
