The Manitou is a 1978 American supernatural body horror film produced and directed by William Girdler. It stars Tony Curtis, Michael Ansara and Susan Strasberg. It is based on the 1976 novel of the same name by Graham Masterton, which was inspired by the concept of manitou in Native American theology, believed to be a spiritual and fundamental life force by members of the Algonquian peoples.

Girdler died in a helicopter accident prior to the film's release.
