Rex Jameson (né Coster; c.11 June 1924 – 5 March 1983) was a British comedian and female impersonator known for his creation and stage persona Mrs Shufflewick. After radio and television success in the 1950s and early 1960s, his career declined sharply because of his alcohol abuse. He returned to a niche celebrity in the 1970s in his drag act at The Black Cap, Camden Town, London.
