Don't Make Waves is a 1967 American sex comedy (with elements of the beach party genre) starring Tony Curtis, Claudia Cardinale, Dave Draper and Sharon Tate. Distributed by Metro-Goldwyn-Mayer, the film was directed by Alexander Mackendrick and is based on the 1959 novel Muscle Beach by Ira Wallach, who also co-wrote the screenplay.

The film depicts a series of romantic triangles between different groupings of the principal cast and supporting players among several backdrops involving Southern California culture (swimming pools, bodybuilding, beach life, fantastic real estate, mudslides, metaphysical gurus, etc.).
