Social Distortion (often known as Social D) is an American punk rock band, formed in 1978 in Fullerton, California by frontman Mike Ness. They are, along with many others, often credited as one of the leading bands of the 1980s punk revival.

The band has remained silent three times and once broke up in 1985, due to seperate interests. However, they reformed around 1987 and have continued being active today, especially after longtime guitarist Dennis Danell passed away from heart failure in 2000. Since their inception the band lineup has been a virtual revolving-door of talent, with many members coming and going; however, Ness has remained.

So far, Social Distortion released six full-length studio albums, one live album, one greatest hits compilation and two DVDs. Their last album, Sex, Love and Rock 'n' Roll, came out on September 28, 2004 and is their first release with current guitarist Jonny "2 Bags" Wickersham, who is Danell's replacement. The band recently made plans to return to the studio to record their seventh album, which is due for release sometime in 2007.
