Petey Wheatstraw (also known as Petey Wheatstraw, the Devil's Son-in-Law) is a 1977 American blaxploitation comedy film written and directed by Cliff Roquemore, and starring comedian Rudy Ray Moore alongside Jimmy Lynch, Leroy Daniels, Ernest Mayhand, Ebony Wright, and Wildman Steve Gallon. It is typical of Moore's other films from the same era, such as Dolemite and The Human Tornado.

In the film, a successful nightclub comedian is murdered by jealous rivals. He is resurrected (along with his killed friends) through a literal deal with the Devil, having agreed to marry the Devil's daughter. He gains magic powers through a magic cane granted to him, and uses them to seek revenge.
