In Greek mythology, Laërtes (Greek: Λαέρτης) was the son of Arcesius an Chalcomedusa. He was the father of Odysseus (who was thus called Λαερτιάδης) and Ctimene by his wife Anticlea, daughter of the thief Autolycus. Laërtes was an Argonaut and participated in the hunt for the Calydonian Boar. Laërtes's title was King of the Cephallenians, which he presumably inherited from his father Arcesius and grandfather Cephalus. His realm included Ithaca and surrounding islands, and perhaps even the neighboring part of the mainland of other Greek city-states.
