In Greek mythology, Gorgophonus (Ancient Greek: Γοργόφονος, "Gorgon-slayer") was one of the nine legitimate sons of Electryon, king of Mycenae, by Anaxo. He fell with his brothers when they met the sons of Pterelaus in the fight over stolen Taphian cattle — before Amphitryon's accidental killing of Electryon opened the throne to Sthenelus.

I.Son of Electryon
Apollodorus catalogues Electryon's sons by Anaxo: Stratobates, Gorgophonus, Phylonomus, Celaeneus, Amphimachus, Lysinomus, Chirimachus, Anactor, and Archelaus. Gorgophonus stands second in that roll — a Mycenaean prince of the Perseid house, brother of Alcmena, through whom the line would pass to Heracles.
The Taphian raid ended the male legitimate line at a stroke: Electryon's sons challenged the sons of Pterelaus over the stolen cattle and the two broods slew one another. Only Licymnius, Electryon's bastard by the Phrygian Midea, survived among the king's sons.
II.Homonyms
This atlas entry (gorgophonus-electryonid) is Electryon's son. The name echoes Gorgophone (gorgophone), Perseus' daughter and Electryon's sister, wife of Perieres — a distinct Perseid princess, not this fallen prince. Not to be confused with Amphimachus the Epeian captain or other Amphimachus homonyms sharing the Electryonid brother-list.
