Jack the Stripper was the nickname given to an unknown serial killer responsible for what came to be known as the London "Nude" Murders, from 1964-1965. His victimology was similar to that of his legendary namesake. He murdered six prostitutes, whose nude bodies were discovered in various locations around London.

Like the Jack the Ripper killings, the "Stripper"'s reign of terror seemed to cease on its own, and there were few solid clues for police to investigate. Though his identity remains unknown, crime writer Donald Rumbelow notes that the killer could have been a young man who committed suicide in South London at the time the murders ended. Though there was never any hard evidence to link him to the crimes (jewelry, etc.), his family found his suicide inexplicable, and his suicide note cryptically said only that he was "unable to take the strain any longer."
