Social Distortion is an American punk rock band formed in 1978 in Fullerton, California. The band currently consists of Mike Ness (lead vocals, lead guitar), Jonny Wickersham (rhythm guitar, backing vocals), Brent Harding (bass, backing vocals), David Hidalgo Jr. (drums), and David Kalish (keyboards).

Emerging from the Orange County hardcore scene of the late 1970s alongside Agent Orange and the Adolescents, Social Distortion went on a temporary hiatus in the mid-1980s, due to Ness's drug addiction and troubles with the law which resulted in extended stints in various rehabilitation centers that lasted for two years. Following their reformation, the band shifted its style to a country, blues, hard rock and early rock and roll–influenced style of punk. Since its inception, the band's lineup has seen significant turnover, with Ness as the only constant member. After 46 years of performing, Social Distortion continues to tour and record music.

To date, Social Distortion has released seven full-length studio albums, two compilations, one live album, and two DVDs. They released two albums—Mommy's Little Monster (1983) and Prison Bound (1988)—before signing a three-album contract with Epic Records in 1989. Social Distortion rose to fame with their 1990 self-titled third album, which produced their well-known hit singles "Ball and Chain", "Story of My Life", and the cover of Johnny Cash's "Ring of Fire", and was certified gold by the RIAA. Many of their later albums, including their second gold record, Somewhere Between Heaven and Hell (1992), have also been well received. Dubbed by Steven Blush as "the Rolling Stones of hardcore," Social Distortion is considered one of the best-selling and most influential punk rock bands, with more than three million albums sold worldwide. The band's most recent studio album is Hard Times and Nursery Rhymes (2011), and they have spent more than a decade working on new material for their forthcoming eighth studio album.
