The Underdogs is a group name used by several different acts in rock and punk: a 1960s garage band from Detroit, Michigan; a 1960s rock band from New Zealand; an UK82 band from England; a band from Hope Valley, Derbyshire; and a band from Aveiro, Portugal. The England-based UK82 line-up includes U.G. on vocals, Col on guitar and vocals, Bill on drums and vocals, and Martin on bass and vocals.

The name is also associated with a 1990s/2000s bluesy-roots group from Florida in the United States. This makes The Underdogs a shared artist name rather than a single act, with uses across garage rock, punk rock, punk, psychedelic rock and related styles.
