The Man Who Haunted Himself is a 1970 British psychological thriller film written and directed by Basil Dearden (his final film prior to his death by car accident in 1971) and starring Roger Moore. It is based on the 1957 novel The Strange Case of Mr Pelham by Anthony Armstrong, and is a variation on the Jekyll and Hyde story.

The story was previously filmed as a 30 minute short for television as part of the series Alfred Hitchcock Presents: Series 1 Episode 11: The Case of Mr Pelham.

In 2011 Moore said his role in the film was his favourite. "It was a film I actually got to act in, rather than just being all white teeth and flippant and heroic."
