Creusa is a daughter of Priam and Hecuba. She married Aeneas. She had only one child with him, a son named Ascanius.
As her husband Aeneas fled from Troy as it fell, Creusa was lost. Aeneas returned to look for her, but could not find her. Creusa's ghost then appeared to him and told him she was now dead. Then, she told him as well of his future travels.
