The Astakides were Naiads (water nymphs) of the Lake Astakos in Bithynia, Eastern Mysia. Presumably the daughters of Lake Astakos or the River Saggarios.

"The Nymphe of the mountain [Didymos] was sore offended at manslaying Nikaia [a Nymphe who slew the shepherd who loved her with an arrow], and lamented over the body of Hymnos; in her watery hall the girl [Naias] of [the river] Rhyndakos groaned, carried along barefoot by the water; the Naiades wept … in the heights of Didymos, gathering near the woods, the Astakides [Nymphai of Astakos] upbraided the Nymphe [Nikaia] of Kybele with her ways, singing the dirge." - Nonnus, Dionysiaca 15.370
