In Greek mythology, Chrysaor (Greek: Χρυσάωρ, Chrysáor, gen.: Χρυσάορος, Chrysáoros; English translation: "he who has a golden sword" [from χρυσός, "golden" and ἄορ, "sword"]) was the brother of the winged horse Pegasus, often depicted as a young man, the son of Poseidon and Medusa, born when Perseus decapitated the Gorgon Medusa.

And when Perseus cut off her head, there sprang forth great Chrysaor and the horse Pegasus who is so called because he was born near the springs of Ocean; and that other, because he held a golden blade in his hands.
