The Naked Ape is a 1973 American comedy film, loosely adapted from the non-fiction book of the same name by Desmond Morris, written and directed by Donald Driver, and starring Johnny Crawford, Victoria Principal, Dennis Olivieri, Diana Darrin, Norman Grabowski, and John Hillerman, with animated segments created by Murakami Wolf Studios. The film was released on August 1, 1973, by Universal Pictures.

The Desmond Morris book had been optioned for a film adaptation in 1968, and aside from some factual consultation, Morris was not involved in the screenplay writing. Initially set up at Universal, after initial screenplay drafts were submitted, the book was deemed unfilmable and was almost sent into turnaround, until Playboy magazine founder Hugh Hefner, who had been producing other film projects at the time, agreed to co-finance the project.

Leading lady Victoria Principal later said that her career momentum was hurt by the film's failure.
