The MGM Oneshot Cartoons are a series of oneshot cartoons, produced by Fred Quimby for MGM's in-house cartoon studio. Many of these shorts were directed by Hugh Harman and Rudolf Ising, as well as future star directors Bill Hanna and Joe Barbera. These shorts were succeeded by the Tex Avery MGM Cartoons, many of which were also oneshot cartoons, although two final oneshots were produced in the 1960s by Chuck Jones for the studio while he was working on his Tom and Jerry shorts.
