Alcinous (; or Ἀλκίνοος, Alkínoös) was, in Greek mythology, a son of Nausithous, or of Phaeax (the son of Poseidon and Corcyra), and father of Nausicaa, Halius, Clytoneus and Laodamas with Arete. His name literally means "mighty mind". He married his brother Rhexenor's daughter after Rhexenor was killed.
