Hercules is a 1997 American animated musical fantasy comedy film produced by Walt Disney Feature Animation for Walt Disney Pictures. It is loosely based on the legendary hero Heracles (known in the film by his Roman name, Hercules), a son of Zeus in Greek mythology. The film was directed by John Musker and Ron Clements, both of whom also produced the film with Alice Dewey Goldstone. The screenplay was written by Clements, Musker, Donald McEnery, Bob Shaw, and Irene Mecchi. Featuring the voices of Tate Donovan, Danny DeVito, James Woods, and Susan Egan, the film follows the titular Hercules, a demigod with super-strength raised among mortals, who must learn to become a true hero in order to earn back his godhood and place in Mount Olympus, while his evil uncle Hades plots his downfall.

Development of Hercules began in 1992 following a pitch adaptation of the Heracles mythological stories by animator Joe Haidar. Meanwhile, Clements and Musker re-developed their idea for Treasure Planet (2002) following the critical and commercial success of Aladdin (1992). Their project was removed from development in 1993, and Musker and Clements joined Hercules later that same year. Following an unused treatment by Haidar, Clements and Musker studied multiple interpretations of Greek mythology before abandoning Zeus's adulterous affair with Alcmene. The project underwent multiple story treatments and a first script draft was inspired by the screwball comedy films of the classic Hollywood era and popular culture of the 1990s. During production, McEnery, Shaw, and Mecchi were brought on board to revise Musker and Clements' script. British cartoonist Gerald Scarfe was recruited as production designer and produced over seven hundred visualization designs of the characters. Research trips to Greece and Turkey provided inspiration for the background designs. Animation for the film was done in California and Paris. Computer animation was used in several scenes, predominantly in the Hydra battle sequence. The production budget was $85 million.

Hercules was released on June 13, 1997, and received generally positive reviews from film critics, with James Woods's performance as Hades receiving particular praise, but the animation (particularly the visual style) and music received a mixed response. The film under-performed in its theatrical release notably in comparison to previous animated Disney films, ultimately earning $252.7 million in box office revenue worldwide. Hercules was later followed by Hercules: The Animated Series, a syndicated Disney television series focusing on Hercules during his time at the Prometheus Academy, and the direct-to-video prequel Hercules: Zero to Hero (1999), which consists of three episodes from the TV series.
