"No One Is Innocent" was the fifth single by the British punk rock band the Sex Pistols. It was released on 30 June 1978. The Pistols had split up early in 1978, losing bassist Sid Vicious and original lead vocalist Johnny Rotten. "No One Is Innocent" was recorded by remaining members Paul Cook and Steve Jones, with vocals performed by Ronnie Biggs, a British criminal notorious for his part in the Great Train Robbery of 1963. At the time of "No One Is Innocent" Biggs was living in Brazil, still wanted by the British authorities, but immune from extradition. The song was credited to Jones and Biggs.

Ronald Arthur Biggs was an English criminal who helped plan and carry out the Great Train Robbery of 1963. He subsequently became notorious for his escape from prison in 1965, living as a fugitive for 36 years, and for his various publicity stunts while in exile. In 2001, Biggs returned to the United Kingdom and spent several years in prison, where his health rapidly declined. He was released from prison on compassionate grounds in August 2009 and died in a nursing home in December 2013.
