Ulysses is a 1954 fantasy-adventure film based on Homer's epic poem Odyssey. The film was directed by Mario Camerini, who co-wrote the screenplay with writer Franco Brusati. The original choice for director was Georg Wilhelm Pabst but he quit at the last minute. The film's cinematographer Mario Bava co-directed the cyclops Polyphemus segment (uncredited).

The Odyssey is one of two major ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. As with the Iliad, the poem is divided into 24 books. It follows the Greek hero Odysseus, king of Ithaca, and his journey home after the Trojan War. After the war, which lasted ten years, his journey from Troy to Ithaca, via Africa and southern Europe, lasted for ten additional years during which time he encountered many perils and all of his crewmates were killed. In his absence, Odysseus was assumed dead, and his wife Penelope and son Telemachus had to contend with a group of unruly suitors who were competing for Penelope's hand in marriage.
