In Greek mythology, Priam, the mythical king of Troy during the Trojan War, supposedly had 18 daughters and 68 sons. Priam had several wives, the primary one Hecuba, daughter of Dymas or Cisseus, and several concubines, who bore his children. There is no exhaustive list, but many of them are mentioned in various Greek myths. Almost all of Priam's children were slain by the Greeks in the course of the war, or shortly after.

The three main sources for the names of the children of Priam are: Homer's Iliad, where a number of his sons are briefly mentioned among the defenders of Troy; and two lists in the Bibliotheca and Hyginus' Fabulae. Virgil also mentions some of Priam's sons and daughters in the Aeneid. Some of the daughters taken captive at the end of the war are mentioned by Pausanias, who in his turn refers to paintings by Polygnotus in the Lesche of Delphi.

Pausanias enlists several more Trojan captive women, who may or may not be daughters of Priam: Clymene, Xenodice, Deinome, Metioche, Peisis, Cleodice. He remarks, however, that of these only Clymene and Deinome were mentioned in literary sources known to him, and that the rest of the names could have been invented by Polygnotus.

• Aeneas – who later led the survivors of Troy – was not a son of Priam, but his father Anchises was Priam's second cousin, making Aeneas Priam's second cousin once removed. Aeneas did, however, marry Priam's daughter Creusa, making him a son-in-law of Priam. Ascanius, the son of Aeneas and Creusa, was himself the ancestor of Romulus and Remus.
• According to Homer:
  • Lycaon is the son of Laothoe.
  • Gorgythion is the son of Castianeira.
• According to Apollodorus:
  • Aesacus's mother is Arisbe, daughter of Merops.
  • Hecuba, daughter of Dymas is the mother of Hector, Paris, Deiphobus, Helenus, Pammon, Polites, Antiphus, Hipponous, Polydorus, Troilus (Troilus may be the son of Apollo), Laodice, Polyxena, Cassandra and Creusa.
• In Mozart's opera, Idomeneo, Ilia is mentioned as another daughter of Priam.
