Strophius (Ancient Greek: Στρόφιος, "slippery fellow, twister") son of Crisus was king of Phocis, husband of Agamemnon's sister (Anaxibia, Astyocheia, or Cydragora), and father of Pylades. He hid the infant Orestes from Clytemnestra and raised him beside Pylades, forging the friendship that carried the Atreid vengeance. The atlas keeps him distinct from the Trojan Strophius father of Scamandrius and from Pylades' own son of the same name.

I.House of Phocis
Strophius was son of Crisus and king in Phocis. Sources disagree on his wife's name: Hyginus calls her Astyoche (sister of Agamemnon); Pausanias, following Asius, names Anaxibia; other notices give Cydragora. By her he fathered Pylades and, in some lists, Astydameia.
When Clytemnestra and Aegisthus murdered Agamemnon, Electra (or another helper) conveyed the child Orestes to Strophius, who hid him and brought him up with Pylades.
II.Orestes and Pylades
During that fosterage Orestes and Pylades became proverbial friends. When Orestes was grown he returned with Pylades to avenge Agamemnon — the pattern Nestor holds up to Telemachus in the Odyssey. Aeschylus, Pindar, and Apollodorus all place Strophius' house at the hinge of the Oresteia.
Homonym care: not the Trojan Strophius whose son Scamandrius Menelaus kills in Iliad 5; not Strophius son of Pylades and Electra; not the companion of Dionysus or the sailor in Menelaus' crew. This node is strophius-phocis alone.
