Eriphyle (/ɛrɪˈfaɪliː/; Ancient Greek: Ἐριφύλη, romanized: Eriphúlē) was a figure in Greek mythology who, in exchange for the necklace of Harmonia (also called the necklace of Eriphyle) given to her by Polynices, persuaded her husband Amphiaraus to join the expedition of the Seven against Thebes. She was then slain by her son Alcmaeon. In Jean Racine's 1674 retelling of Iphigenia at Aulis, she is an orphan whose real name turns out to be Iphigenia as well; despite her many misdeeds, she rescues Iphigenia the daughter of Agamemnon.
