In Greek mythology, Coroebus (Greek: Κόροιβος) was the son of King Mygdon of Phrygia. He came to the aid of Troy during the Trojan War out of love for Princess Cassandra. During the Sack of Troy, Coroebus convinced some of his fellow soldiers, including Aeneas, to dress in enemy armor to disguise themselves. When he tried to defend Cassandra from rape by Ajax the Lesser, he was killed, either by Peneleos, Diomedes or Neoptolemus. He was ultimately killed by Peneleos according to Virgil's Aeneid.
