Polydorus or Polydoros is the youngest son of Priam in the mythology of the Trojan War. While Homer states his mother is Laothoe, later sources state his mother is Hecuba. Polydorus is an example of the fluid nature of myth, as his role and story vary significantly in different traditions and sources.

In Greek mythology, Priam was the legendary and last king of Troy during the Trojan War. He was the son of Laomedon. His many children included notable characters such as Hector, Paris, and Cassandra.
