Daffy Duck's Fantastic Island (also known as Daffy Duck's Movie: Fantastic Island) is a 1983 American animated anthology film directed by Friz Freleng and Phil Monroe with a compilation of classic Warner Bros. cartoon shorts and animated bridging sequences, hosted by Daffy Duck and Speedy Gonzales. This was the first Looney Tunes compilation film to center on Daffy Duck, as the previous ones had centered on Bugs Bunny. The premise of the framing animation was a general parody of the popular 1970s/1980s television series Fantasy Island, with Daffy Duck and Speedy Gonzales playing caricatures of that series' principal characters, Mr. Roarke and Tattoo (respectively).

A note in the end credits dedicates the film to animator and story man, John Dunn, "who inspired it." Dunn died of heart failure in San Fernando, California on January 17, 1983; six months before the film's release.
