David Fleischer (July 14 1894 - June 25 1979) was a German-American animator, film director, and film producer, best known as a co-owner of Fleischer Studios with his older brother Max Fleischer. He was a native of New York City.

Dave Fleischer was notable during the brothers' early days as the rotoscope model for their first character, Koko the Clown. he wnet on to become director and later producer of the studio's output. Although he is credited as "director" of ever film released by the Fleischer studio from 1921 to 1942, the lead animators actually performed directorial duties, and Fleischer served that of a producer.

In January 1942, Fleischer, no longer able to cooperate with his brother, left Fleischer Studios for the Screen Gems studio at Columbia Pictures. Fleischer Studios was bankrupted when Paramount called the loan it had given the studio; now owned wholly by Paramount, it was re-organized as Famous Studios.

In the late-1940s, Fleischer moved over to Universal, where he became a special effects expert and general problem-solver, working on films such as Francis, The Birds, and Thoroughly Modern Millie. He died on June 25, 1979 of a stroke in Woodland Hills, California.
