Of Ithaca, father of Antinoüs. Once when he had attacked the Thesprotians, the allies of the Ithacans, Odysseus protected him from the indignation of the people of Ithaca. When Odysseus after his long wanderings returned home, Eupeithes wanted to avenge the death of his son Antinous, who had been one of Penelope's suitors and was slain by Odysseus. He accordingly led a band of Ithacans against Odysseus, but fell in the struggle. (Hom. Od. xvi. 436, xxiv. 469, 523.)
