The name Nausithous (; Ancient Greek: Ναυσίθοος Nausíthoos) is shared by the following characters in Greek mythology:
- Nausithous, the king of the Phaeacians who reigned in the generation before Odysseus washed ashore on their home island of Scherie(The contemporary king at the time of odysseus's arrival was Alcinous). He was the son of the god Poseidon and Periboia, the daughter of the Giant king Eurymedon. According to Homer, Nausithous led a migration of Phaeacians from Hypereia to the island of Scheria in order to escape the lawless Cyclopes. He is the father of Alcinous and Rhexenor. Alcinous would go on to marry his niece, Rhexenor's daughter Arete. One source relates that Heracles came to Nausithous to get cleansed after the murder of his children; during his stay in the land of the Phaeacians, the hero fell in love with the nymph Melite and conceived a son Hyllus with her.
- Nausithous, one of the two sons born to Odysseus by Calypso, the other one being Nausinous. According to Hyginus, Nausithous was a son of Odysseus and Circe; his brother was Telegonus.
