Chris Clark (born 1945/6) is a British amateur crime writer who writes chiefly about serial killers and their supposed links to unsolved crimes. He is a retired police intelligence officer who worked in the King's Lynn area for Norfolk Police, although his career was somewhat unsuccessful and he had three applications to join the new National Criminal Intelligence Service rejected in 1993, with the commanding officers unimpressed by his record and applications. In 2022, his book Yorkshire Ripper: The Secret Murders, which was jointly written with journalist Tim Tate and alleged links between Peter Sutcliffe and unsolved murders, was made into an ITV prime-time documentary series of the same name.
