The following list is a filmography of all animated short subjects distributed by the Metro-Goldwyn-Mayer (MGM) motion picture studio through Loew's Incorporated between 1930 and 1958 and between 1961 and 1967.

William Hanna and Joseph Barbera were directors of Tom and Jerry from 1940 to 1958; subsequent cartoons were briefly produced by Gene Deitch and later by Chuck Jones from 1963 to 1967. As well, Rudolf Ising was the producer of Tom and Jerry's Puss Gets the Boot; subsequent cartoons were produced by Fred Quimby through 1955. Quimby retired in 1955 and from 1955 to 1957, Hanna and Barbera produced the shorts until the in-house cartoon studio closed in 1957, and the last cartoon was released in 1958. After a three-year hiatus, Tom and Jerry was brought back in 1961, and Tanner the Lion was brought back in 1963. The last MGM cartoon was released in 1967 as The Bear That Wasn't.

Between 1935 and 1957, MGM ran an in-house cartoon studio which produced shorts featuring the characters Barney Bear, George and Junior, Screwy Squirrel, Red Hot Riding Hood & The Wolf, Droopy and best of all, Tom and Jerry. Outside producers included Ub Iwerks (1930–34, via Iwerks Studio), Hugh Harman and Rudolf Ising (1934–5, via Harman-Ising Productions), William L. Snyder (1961–62, via Rembrandt Films), and Chuck Jones (1963–67, via MGM Animation/Visual Arts).

During this era, Iwerks Studio produced 52 cartoons for MGM, one of those cartoons being held over to the Happy Harmonies era. None of the shorts have credited directors, but all of these listed cartoons are known to be directed by Ub Iwerks, with Carl W. Stalling as the composer.

Many of the cartoons are also in the public domain, with some exceptions such as Fiddlesticks and Davy Jones' Locker.
