Jack Woltz is a fictional character from the novel The Godfather and the 1972 film adaptation.

He is a movie producer who refuses to cast the singer/actor Johnny Fontane in his movie due to his jealousy over Fontane's role in the break up of one of his previous relationships. Fontane asks Don Vito Corleone, who is his godfather, as well as the head of an organized crime family, to lean on Woltz. Corleone sends his consigliere, Tom Hagen, to Hollywood to "reason" with Woltz. At first Woltz becomes enraged and refuses to bargan wtih Hagen. Later, after researching exactly who Hagan worked for, he appeared more eager to listen. But in the end he still refused to cast Fontane. Woltz is finally persuaded in perhaps one of the most famous scenes in movie history; when he wakes up the next morning to find the decapitated head of his prized racehorse, Khartoum, in his bed.

In the novel, Woltz is portrayed as a pedophile who routinely abuses young girls who audition for his movies. This side to the character is largely left out of the movie but is implied in a line of dialogue.

In the film, he is potrayed by John Marley.
