Nat Jackley (16 July 1909 - 17 September 1988) was an English comic actor starring in variety, film and pantomime from the 1920s to the mid-1980s whose trademark rubber-neck dance, skeletal frame and peculiar speech impediment made him a formidable and funny comedian and pantomime dame. His later years were spent as a character actor in films and television.

A native of Sunderland, Nathaniel Tristram Jackley Hirsch was born into a theatrical family. His father George Jackley (1885-1950) was a comic actor who was the leading comedian for the Melville Brothers at the Lyceum Theatre during the interwar years.

George, himself, was the son of Nathan Jackley who, with his own troupe, The Jackley Wonders, performed in circuses throughout Europe and the United States. His brother David was an actor and his wife, Marianne Lincoln, was scriptwriter and Nat's comedy foil. Nat Jackley was also a member of the Freemasons.
