In Greek mythology, the name Iphinoe (Ἰφινόη) may refer to:
Iphinoe, one of the daughters of 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, daughter of Nisos and Abrota, and mother of Timalcus, Evippus and Evaechme by Megareus of Onchestus.
Iphinoe, daughter of Alcathous by either Pyrgo or Evaechme (daughter of the precedent). She died a maiden, and it was a custom for the girls of Megara to bring libations to her tomb and to dedicate a lock of hair to her before their marriage.
Iphinoe, in one version, mother of Daedalus by Metion.
Iphinoe, a Lemnian, herald of Hypsipyle, who welcomed the Argonauts upon their arrival at Lemnos.
Iphinoe, daughter of Antaeus and Tinjis, mother of Palaemon by Heracles.
