Charles Arthur Salvador (born Michael Gordon Peterson; 6 December 1952; formerly known as Charles Ali Ahmed) better known by his professional name of Charles Bronson, is a British criminal, with a violent and notorious life as a prisoner. He has spent periods detained in the Rampton, Broadmoor, and Ashworth high-security psychiatric hospitals.

First arrested as a petty criminal, he was convicted and sentenced in 1974 to seven years' imprisonment for armed robbery. Further sentences were imposed because of attacks on prisoners and guards. Upon his release in 1987, he began a bare-knuckle boxing career in the East End of London. His promoter thought he needed a more suitable name and suggested he change it to Charles Bronson, after the American actor. He was returned to prison in 1988 on conviction concerning another robbery. He is a violent prisoner, and has taken numerous hostages in the course of confrontations with guards, resulting in sentences of life imprisonment. He has been held at times in each of England's three special psychiatric hospitals.

Bronson has been featured in books, interviews, and studies of prison reform and treatment. He has said: "I'm a nice guy, but sometimes I lose all my senses and become nasty. That doesn't make me evil, just confused." He was the subject of the 2008 film Bronson, a biopic based loosely on his life, starring Tom Hardy as Bronson, with Kairon Scott Busuttil and William Darke playing him as a child.

Bronson has written many books about his experiences and the famous prisoners he has met throughout his incarceration. A fitness fanatic who has spent many years in segregation from other prisoners, Bronson wrote a book about exercising in confined spaces. He is an artist; paintings and illustrations of prison and psychiatric hospital life have been exhibited and won him awards.

In 2014, he changed his name again, this time to Charles Salvador, in a mark of respect to Salvador Dalí, one of his favourite artists. The Charles Salvador Art Foundation was founded to promote his artwork and "help those in positions even less fortunate than his own" to participate in art. In 2023, his application for parole was rejected.
