Howard Peter Guber (b. 2 March 1942 in Newton, Massachusetts) is an American film producer and executive.

Peter Guber was formerly the studio chief at Columbia Pictures and chairman and CEO of Sony Pictures. He is now chairman of Mandalay Entertainment, which he founded in 1995. The films he has produced—including Midnight Express, The Color Purple, Rain Man, and Batman, among many others—have reportedly earned more than $3 billion in worldwide revenue, and have been nominated for numerous Academy Awards.

Guber resigned from Columbia in 1976 and formed Filmworks, Inc. In 1977, he merged his company with Casablanca Records headed by Neil Bogart to form Casablanca Record and Filmworks, Inc.. At Casablanca, Guber focused on television production. At the same time, he independently produced The Deep for Columbia and the Academy Award-nominated film Midnight Express. This period of Casablanca's history and Guber's part in it was also marked by notorious excesses and was written up in the best selling book Hit Men by Frederic Dannen - a series of chapters telling stories from the high point of the "sex, drugs and rock 'n roll" period of recorded music in the late sixties and seventies. Guber won his first of two National Association of Theater Owners Producer of the Year award in 1978.
