The Twelve Tasks of Asterix (Les Douze travaux d'Astérix) is a 1976 English/French animated feature film based on the Asterix comic book series, and the third in the animated franchise. René Goscinny and Albert Uderzo, the creators of the series, wrote the story and directed the film themselves; with co-direction by Pierre Watrin and the screenplay co-written by Pierre Tchernia, a friend of Goscinny and Uderzo. The film was directed, produced and animated at Goscinny and Uderzo's own animation studio, Studios Idéfix, and is the only Asterix animated film that used xerography, instead of traditional inkers.

At the time of its release, the film received mixed reviews since its tone is more cartoony and frequently breaks the fourth wall. Nowadays, its reception is more favourable, with it often being cited as one of the best Astérix films, even reaching the status of a cult classic.

It was the only Asterix film (animated or live-action) to be based on an original screenplay rather than on material from any of the comic book stories until the release of Asterix: The Secret of the Magic Potion in 2018. It was later adapted into a comic book as well by Albert Uderzo's brother, Marcel Uderzo, as an illustrated text story book and a series of twelve books for young readers.
