In Greek and Roman mythology, Creusa (Ancient Greek: Κρέουσα, romanized: Kreousa) is the wife of Aeneas, and the mother of Ascanius. According to Apollodorus, she is the daughter of Priam and Hecuba. A number of sources describe her presence during the sack of Troy, with her often fleeing the city alongside her husband. In Virgil's Aeneid, Creusa is lost in the confusion while their family is trying to escape, leading Aeneas to turn back to look for her; there he is met with her shade, which foretells of his future journey to Hesperia, where he is told he will marry a different woman.
