Animal Crackers is a musical play with music and lyrics by Bert Kalmar and Harry Ruby and a book by George S. Kaufman and Morrie Ryskind. The musical starred the Marx Brothers and is set at the Long Island Home of Mrs. Rittenhouse; a character portrayed by Margaret Dumont in the 1928 production on Broadway.

The lyrics and music of several songs in Animal Crackers entered the public domain in the United States in 2024. The full script, copyrighted in 1929, entered the public domain in the United States in 2025.

Animal Crackers opened on Broadway on October 23, 1928, at the 44th Street Theatre, and closed April 6, 1929, running for 191 performances. The musical was produced by Sam H. Harris, staged by Oscar Eagle, and starred the four Marx Brothers and Margaret Dumont in the Brothers' second Broadway hit. Hermes Pan appeared as a chorus boy.

In 1930, Paramount Pictures released a film version of the play with the Marx Brothers and some of the principal actors repeating their roles from the stage production, but with most of the musical numbers cut.

After The Cocoanuts ran for almost three years at the Lyric Theatre, the "anarchic" Animal Crackers became the third and final Broadway show for the Marx Brothers (I'll Say She Is was the first), after which they transitioned to making films. Vaudeville's heyday was nearly over, as talking pictures were beginning to become popular. The Marx Brothers performed Animal Crackers on stage in the evenings, while during the day they were busy filming The Cocoanuts at Paramount's Astoria Studios in Astoria, Queens.

The song list for the show is as follows:
