In Greek mythology, Agapenor was the leader of the Arcadians in the Trojan War. A son of Ancaeus and grandson of Lycurgus, he reigned as king of Arcadia and was numbered among the suitors of Helen. He received sixty ships from Agamemnon to carry his landlocked Arcadians to Troy, and was among the warriors hidden inside the Trojan Horse. On the voyage home a storm drove him to Cyprus, where he founded the city of Paphos and built its famous temple of Aphrodite.
