The Plank is a 1967 British slapstick comedy film (51 minutes) made by Associated London Films. It follows the misadventures of two builders who require a floorboard. It was written and directed by Eric Sykes, and produced by Jon Penington. The story was based on an episode of Eric Sykes' BBC comedy series Sykes and a... from 1964, called "Sykes and a Plank".

Although not strictly a silent film, it is unusual in having little dialogue; instead, the film is punctuated by grunts, other vocal noises and sound effects.

The cast features many of the top comedians and comic actors of the time.
