Troezen was one of the children of Pelops and Hippodamia in Greek mythology. Along with his brother Pittheus, Troezen went to live at King Aetius' court, who ruled over Hyperea and Anthea. When they grew up, they succeeded Aetius in the throne. After Troezen's death, Pittheus merged the two cities and named the new area after his brother.
