In Greek mythology, Strophius /ˈstroʊfiəs/, son of Crisus, was a King of Phocis, husband of the sister of Agamemnon (whose name was either Anaxibia, Astyocheia or Cydragora) and, by her, father of Pylades and Astydameia. When Orestes was hiding from his murderous mother, Clytemnestra, Strophius hid him. During this time, Orestes and Pylades became great friends.
Strophius was also the name of one of Pylades' sons with Electra, Orestes' sister. Pylades and Electra's other son was Medon.
Yet another Strophius was the father of the Trojan Scamandrius, who was killed by Menelaus.
