Lawrence Weingarten (December 30, 1897 – February 5, 1975) was an American film producer. He was best known for working for Metro-Goldwyn-Mayer and producing some of the studio's most prestigious films such as Adam's Rib (1949), I'll Cry Tomorrow (1955) and Cat on a Hot Tin Roof (1958). During his career, Weingarten was nominated for an Academy Award in 1959 and was given the Irving G. Thalberg Memorial Award in 1974, which was presented by Katharine Hepburn in her first and only appearance at the Oscars ceremony to present the award to her long time friend Weingarten. Whenever she won an Oscar, she always had either the presenter or another person associated with her film accept it on her behalf. Upon taking the stage, she received a standing ovation, to which she replied "I'm living proof that a person can wait forty-one years to be unselfish."
