The Gallopin' Gaucho is a 1928 American animated short film and the second short film featuring Mickey Mouse to be produced, following Plane Crazy and preceding Steamboat Willie. The Disney studios completed the silent version in August 1928, but did not release it in order to work on Steamboat Willie. The Gallopin' Gaucho was released, with sound, after Steamboat Willie on December 30 of the same year.

Both Mickey and Minnie Mouse had already made their initial debuts with the test screening of Plane Crazy on May 15, 1928, but that film had failed to catch the attention of distributors when first produced as a silent film. The Gallopin' Gaucho was a second attempt at success by co-directors Walt Disney and Ub Iwerks. The latter also served as the sole animator for it.

Roy O. Disney wrote down the total budget of the short in his ledger book, which ended up costing $4,249.73, which was about $720 more than the costs of Plane Crazy's $3,528.50 budget.

The short was intended as a parody of Douglas Fairbanks's The Gaucho, a film first released on November 21, 1927. Following the original film, the events of the short take place in the Pampas of Argentina with Mickey cast as the gaucho of the title.

The short entered the US public domain on January 1, 2024.
