In Greek mythology, Nausinous (, Nausinoos) was the son of Odysseus and Calypso. While stranded on Ogygia, Odysseus was forced to become the lover of Calypso. According to Hesiod, this union resulted in two sons, named Nausinous and Nausithous. Neither Nausinous nor his brother are mentioned in Homer’s Odyssey. Classical lore suggests some Greeks believed that Telemachus would later voyage to the island of Calypso and there marry his half-sister, the child of Calypso and Odysseus.
