Watermelon Man is a 1970 American comedy film directed by Melvin Van Peebles and starring Godfrey Cambridge, Estelle Parsons, Howard Caine, D'Urville Martin, Kay Kimberley, Mantan Moreland, and Erin Moran. Written by Herman Raucher, it tells the story of an extremely bigoted 1960s-era white insurance salesman named Jeff Gerber, who wakes up one morning to find that he has become black. The premise for the film was inspired by Franz Kafka's Metamorphosis, and by John Howard Griffin's autobiographical Black Like Me.

Van Peebles' only studio film, Watermelon Man was a financial success, but Van Peebles did not accept Columbia Pictures' three-picture contract, instead developing the independent film Sweet Sweetback's Baadasssss Song. The music for Watermelon Man, written and performed by Van Peebles, was released on a soundtrack album, which spawned the single "Love, That's America".
