Alice in Wonderland is a 1951 American animated feature produced by Walt Disney and based primarily on Lewis Carroll's Alice's Adventures in Wonderland with a few additional elements from Through the Looking-Glass. Thirteenth in the Walt Disney Animated Classics series, the film was released in New York City and London on July 29, 1951 by RKO Radio Pictures. The film features the voices of Kathryn Beaumont as Alice (also voice of Wendy Darling in the later Disney feature film, Peter Pan) and Ed Wynn as the Mad Hatter.

Made under the supervision of Walt Disney himself, this film and its animation are often regarded as some of the finest work in Disney studio history, despite the lackluster, even hostile, reviews it originally received, especially in the United Kingdom.
