Antenor (Greek: Ἀντήνωρ, Antḗnōr) was a counselor to King Priam of Troy in the legendary Greek accounts of the Trojan War.
Antenor was variously named as the son of the Dardanian noble Aesyetes by Cleomestra or of Hicetaon.
Antenor was one of the wisest of the Trojan elders and counsellors. He was the husband of Theano, daughter of Cisseus of Thrace, who bore him at least one daughter, Crino, and numerous sons, including Archelochus, Acamas, Glaucus, Helicaon, Laodocus, Coön, Polybus, Agenor, Iphidamas, Laodamas, Demoleon, Eurymachus, Hippolochus, Medon, Thersilochus, and Antheus (most of whom perished during the Trojan War). He was also the father of a son, Pedaeus, by an unknown woman. According to numerous scholars, Antenor was actually related to Priam.
In the Homeric account of the Trojan War, Antenor advised his countrymen to return Helen to her husband and otherwise proved sympathetic to a negotiated peace with the Greeks. In later developments of the myths, particularly per Dares and Dictys, Antenor was made an open traitor, unsealing the city gates to the enemy. As payment, his house—marked by a panther skin over the door—was spared during the sack of the city.
