Amphion the Pirate (died 431 BC) was a Greek pirate captain who operated out of Corinth during the Peloponnesian War. In 431 BC, he helped the hetaera Kleio escape from her service as a courtesan, but Anthousa sent Kassandra of Sparta to "rescue" her from the pirates. Kassandra immobilized Amphion's ship before slaying him and several other pirates, and she then took Kleio back to Erinna.
