In Greek mythology, Amphimachus (/æmˈfɪməkəs/; Ἀμφίμαχος) is a name attributed to multiple individuals.
Amphimachus was the son of Zeus (son of Actor) and Theronice, daughter of Dexamenus. He was one of the leaders of the Elean contingent at the Trojan War (the other was Thalpius, son of Eurytus) and was slain by Hector.
Amphimachus was the son of Nomion. He and his brother Nastes were captains of the Carian contingent on the side of the Trojans in the Trojan war. Either he or his brother were killed by Achilles; according to the commentary to the Iliad by Thomas D. Seymour, his brother Nastes was the one killed and of whom the armour and golden ornaments were subsequently stripped off.
Amphimachus was the son of Electryon and Anaxo, killed (along with most of his brothers) by the sons of Pterelaus.
Amphimachus was the son of Polyxenus and was also the king of Elis. He was named after Amphimachus, son of Cteatus. He was the father of Eleius, his successor.
Amphimachus was one of the suitors of Penelope from Dulichium. He was ultimately killed by Odysseus. Another suitor of Penelope named Amphimachus was from Ithaca. He too was ultimately killed by Odysseus.
