Jim'll Fix It is a British television series broadcast by the BBC between May 1975 and July 1994 and was devised and presented by Jimmy Savile and produced by Roger Ordish. The show encouraged children to write in a letter to Savile with a "wish" that would come true at the end of each episode, upon which the child would be granted a medal. Notable celebrity guests appearing on the show include Muhammad Ali, Tom Baker, and Peter Cushing.

Jim'll Fix It was briefly revived in 2007 as Jim'll Fix It Strikes Again and later had a television special air in 2011.

Shortly after Savile's death in 2011, allegations of child sex abuse against Savile arose relating to the television series.
