Santa Claus (sometimes also known as Santa Claus vs. the Devil) is a 1959 Mexican fantasy film directed by René Cardona and co-written with Adolfo Torres Portillo. In the film, Santa Claus works in outer space and battles with a demon named Pitch, sent to Earth by Lucifer to ruin Christmas by killing Santa and "making all the children of the Earth do evil".

In 1960, a slightly edited English language dubbing of the film was produced for release in the United States under the direction of Ken Smith. The film achieved wider recognition and a cult following after it was lampooned on a 1993 episode of Mystery Science Theater 3000.
