In Greek mythology, Astyanax (; Astyánax, "protector of the city") was the son of Hector, Crown Prince of Troy and Princess Andromache of Cilician Thebe. His birth name was Scamandrius (in Greek Σκαμάνδριος or Σκάμανδρος, after the river Scamander), but the people of Troy nicknamed him Astyanax (i.e. high king, or overlord of the city), because he was the son of the city's great defender (Iliad VI, 403) and the heir apparent's firstborn son.
