Alcyone (//; Ancient Greek Ἁλκυόνη Αlkuónē, derived from alkyon αλκυων "kingfisher") in Greek mythology, was the name of one of the Pleiades, daughters of Atlas and Pleione or, more rarely, Aethra. She attracted the attention of the god Poseidon and bore him several children, variously named in the sources: Hyrieus, Lycus, Hyperenor, and Aethusa; Hyperes and Anthas; Glaucus; and Epopeus. There are various etymological interpretations of her name's origin.
