Deep End is a 1970 psychological comedy drama film directed by Jerzy Skolimowski and starring Jane Asher, John Moulder Brown and Diana Dors. It was written by Skolimowski, Jerzy Gruza and Boleslaw Sulik. The film was an international co-production between West Germany and the United Kingdom. Set in London, the film centers on a 15-year-old boy who develops an infatuation with his older, beautiful co-worker at a suburban bath house and swimming pool.

The film premiered at the Venice Film Festival on 1 September 1970. Deep End, considered a cult classic, went unreleased for many years due to rights issues. In 2011, it was given a digital restoration with the cooperation of the British Film Institute and was released in theaters and on home media.
