The Idiot (Japanese: 白痴, Hepburn: Hakuchi) is a 1951 Japanese film directed and written by Akira Kurosawa. It is based on the 1869 novel The Idiot by Fyodor Dostoevsky. The original 265-minute version of the film, faithful to the novel, has been long lost. A nearly three-hour release, reflecting a 100-minute studio-imposed cut, currently survives as the most complete version of the film available for contemporary audiences.

The film stars Setsuko Hara who plays the part of Taeko Nasu, the beautiful mistress of Tohata. The characters are involved in a weblike plot of intersecting relationships.
