In Greek mythology, the name Iphinoe (Ancient Greek: Ἰφινόη) may refer to: * Iphinoe, an Argive princess as one of the daughters of King Proetus and Stheneboea. She and her sisters Lysippe and Iphianassa were driven mad (either because they didn't accept the rites of Dionysus, or else because they disparaged a wooden statue of Hera) and ran off into the wilderness like maenads. Melampus had to pursue them in order to provide a cure; Iphinoe died in the pursuit, but her sisters did eventually recover their wits through purification rites. * Iphinoe, a Megarian princess as daughter of King Nisos and Abrota of Onchestus, thus sister to Eurynome and Scylla. She was the mother of , Evippus and Evaechme by Megareus of Onchestus. * Iphinoe, also a Megarian princess as daughter of King Alcathou
