The Adolescents are an American punk band formed in 1980 in Fullerton, California. It is a punk supergroup, made up of early members of Agent Orange and Social Distortion. Along with Bad Brains, Black Flag, Minor Threat, and many others, they are often credited as one of the leading bands of the 1980's punk revival.

For 29 years after its inception, the Adolescents have had many member changes. The band broke up and reformed twice, sometimes with different guitarists, bass players and/or drummers. Their first break up was sometime after the release of their 1981 self-titled debut release, which is often considered an influential punk rock album, when some members of the band were involved in their own projects, including Agent Orange and D.I.. However, the Adolescents reunited in 1986 and released two more albums (Brats in Battalions in 1987 and Balboa Fun Zone in 1988) before splitting up again in 1989. The band once again reunited for good in 2001 for a 20th anniversary tour and have continued performing ever since. They released O.C. Confidential, their first studio album in 17 years in 2005, followed by 2010's upcoming album The Fastest Kid Alive.
