Achiroë or Anchirrhoë (Greek: Ἀχιρ(ρ)όη), or according to Apollodorus Anchinoë (Ἀγχινόη),[1] which is perhaps a mistake for Anchiroë, was in Greek mythology a naiad, a daughter of the river-god Nilus. She was also the wife of Belus, by whom she became the mother of Aegyptus and Danaus, and, according to some accounts, Cepheus, and Phineus.[2] According to the scholiast on Lycophron,[3] she was the consort of Sithon, son of Ares, and bore him two daughters, Pallene and Rhoeteia, from whom two towns derived their names.[4][5]
