In Greek mythology, Laodice (English pronunciation: /leɪˈɒdəˌsi/; Ancient Greek: Λαοδίκη, Greek pronunciation: [la.odíkɛː], "people-justice") was the daughter of Priam of Troy and Hecuba. She is described as the most beautiful of Priam's daughters.
Before the outbreak of the Trojan war Laodice fell in love with Acamas, son of Theseus, who had come to Troy to try to recover Helen through diplomatic means. She became pregnant and bore him the son Munitus. Munitus was given to Acamas' grandmother Aethra, who was then a slave to Helen. After the war had ended, Acamas took his son with him. Much later, Munitus was bitten by a snake while hunting with his father in Thrace and died.
The Iliad mentions Laodice as the wife of Helicaon, son of Antenor, although according to Hyginus she was the wife of Telephus, king of Mysia and son of Heracles.
According to the Bibliotheca and several other sources, in the night of the fall of Troy Laodice feared she might become one of the captive women and prayed to the gods. She was swallowed up in a chasm that opened on the earth. There is no information on which deity she prayed to but Persephone seemed to have provided the chasm. There is no information on what happened after she was swallowed. The assumption is that she was transported alive to Hades.
