Squirm is a 1976 American natural horror film written and directed by Jeff Lieberman in his feature-film directing debut, starring Don Scardino, Patricia Pearcy, R. A. Dow, Jean Sullivan, Peter MacLean, Fran Higgins and William Newman. The film takes place in the fictional town of Fly Creek, Georgia, which becomes infested with carnivorous worms after an electrical storm. Lieberman's script is based on a childhood incident in which his brother fed electricity into a patch of earth, causing earthworms to rise to the surface.

Most of the financing came from Broadway producers Edgar Lansbury and Joseph Beruh. Millions of worms were used over the five-week filming in Port Wentworth, Georgia; worms were brought in from Maine to augment local supplies. Makeup artist Rick Baker provided the special effects, using prosthetics for the first time in his career. After American International Pictures picked up Squirm for distribution, it was edited to remove the most graphic scenes in an unsuccessful attempt to lower its "R" rating to "PG". The film was a commercial success, but opened to lukewarm reviews. It has since become a critical favorite and a cult classic.
