Smile is a 1975 American satirical comedy film directed by Michael Ritchie, written by Jerry Belson, and starring Bruce Dern, Barbara Feldon, Michael Kidd, and Geoffrey Lewis. The film focuses on various personalities involved in a beauty pageant in Santa Rosa, California, and satirizes small-town America and its peculiarities, hypocrisies and artifice within and around the pageant.

Filmed on location in Santa Rosa, the film premiered at the USA Film Festival in Dallas, Texas, and opened theatrically in Los Angeles in July 1975 before screening at the 1975 New York Film Festival. Though it received generally favorable reviews from critics, the film was a box-office flop. In the years since its release, Smile went on to develop a cult following. It was adapted into a 1986 Broadway musical of the same name with songs by Marvin Hamlisch and Howard Ashman.
