In Greek mythology, Callirrhoe was the name attributed to seven different characters.
One of them was an Oceanid or a Naiad, daughter of Oceanus and Tethys, and one of the nymphs that followed Persephone. This figure had three consorts: Chrysaor, with whom she gave birth to Geryon and Echidna; Poseidon, giving birth to Minyas; and Nilus, with whom she had Chione.
Another Callirrhoe was the daughter of the river god Achelous, who was married to Alcmaeon. Her husband went to Psophis in order to retrieve the Necklace of Eriphyle for her wife, but the brothers of his first wife killed him. Callirrhoe then asked Zeus to turn her sons, Amphoterus and Acarnas, into men, in order to avenge their father's death.
A different figure with the same name was the daughter of Scamander, who married Troas and had four children; Ganymedes, Ilus, Assaracus, and Cleopatra. The other characters named Callirrhoe played minor roles in Greek mythology.
