In Greek mythologyElephenor was the son of Chalcodon and king of the Abantes of Euboea. He received the sons of Theseus of Athens, Acamas and Demophon, when they fled the usurper Menestheus. He was the leader of the Euboean force of fifty ships which joined the Greek expedition to Troy, but on the day the truce was broken by Pandarus, was killed by Agenor whilst trying to drag off the body of Echepolus. On their way home, Elephonor's men were driven off course and shipwrecked off the coast of Epirus, where they founded the city of Apollonia.
