Eraserhead (released in France as The Labyrinth Man) is a 1977 surrealist-horror film written and directed by David Lynch. The film stars Jack Nance and Charlotte Stewart. Eraserhead initially polarized and baffled many critics and movie-goers, but over time the film has become a cult classic.

In 2004, the film was deemed "culturally significant" by the United States Library of Congress and selected for preservation in the National Film Registry. Lynch has described his film as a "dream of dark and troubling things."

Eraserhead is considered a difficult film to understand and is open to various interpretations. For example, the review at DVD Verdict offers at least three interpretations. The story does not have a strictly linear plot, it is punctuated with fantasy/dream sequences of differing lengths, and the boundary between these sequences and the primary narrative strand is often blurred. Many have interpreted it as a visual-sound experience rather than a narrative or story, a film that is more about conveying a very specific and powerful mood and atmosphere. Lynch has said he has yet to read an interpretation of the film that is the same as his own.
