Stuart Cornfeld (November 13, 1952 – June 26, 2020) was an American film producer.

He was business partners with Ben Stiller in the company Red Hour Productions.

He attended the University of California, Berkeley in the early 1970s, and graduated with a degree in Psychology.

[citation needed] During his time at AFI, one of his classmates was actress Anne Bancroft, who was preparing to make her first film as a director, Fatso.

The appearance and personality of Les Grossman, the hotheaded and foul-mouthed Hollywood producer played by Tom Cruise in Stiller's film Tropic Thunder, is reportedly based in part on Cornfeld.
