Hair is a 1979 musical anti-war comedy-drama film directed by Miloš Forman and adapted for the screen by Michael Weller, based on the 1968 Broadway musical Hair: The American Tribal Love-Rock Musical. Set against the backdrop of the hippie counterculture of the Vietnam era, the film focuses on a Vietnam War draftee who meets and befriends a "tribe" of hippies while en route to the army induction center. The hippies and their leader introduce him to marijuana, LSD, and their environment of unorthodox relationships and draft evasion.

The film stars an ensemble cast including John Savage, Treat Williams, Beverly D'Angelo, Annie Golden, Dorsey Wright, Don Dacus, Cheryl Barnes and Ronnie Dyson. Dance scenes were choreographed by Twyla Tharp and were performed by Tharp's dancers. Hair was nominated for two Golden Globes: Best Motion Picture – Musical or Comedy, and New Star of the Year in a Motion Picture (for Williams).
