In Greek mythology, Chrysaor ("golden falchion") was a giant, the son of Poseidon and Medusa. He was conceived on the floor of a temple to Athena who, enraged at the desecration, turned Medusa into a Gorgon. As such, Chrysaor and his brother, the winged horse, Pegasus, were not born until Perseus chopped off Medusa's head. They were born from the drops of blood.

Chrysaor had one son, Geryon.
