Nicaea was wife of Alexander, tyrant of Corinth during the reign of Antigonus Gonatas. After the death of her husband, who was thought to have been poisoned by the command of Gonatas, Nicaea retained possession of the important fortress of Corinth: but Antigonus lulled her into security by offering her the hand of his son Demetrius in marriage, and took the opportunity during the nuptial festivities to surprise the citadel. She is probably the same person mentioned by Sudas (s.v. Euphorion) as patronising the poet Euphorion of Chalcis , though that author calls her husband ruler of Euboea, instead of Corinth.
