In Greek mythology, Actaea or Actea (Ancient Greek Ἀκταία, "dweller on coasts") is the Nereid of the rocky shore, one of the fifty sea-nymph daughters of Nereus and the Oceanid Doris. Homer names her among the sisters who gather around Thetis in grief for Achilles after Patroclus' death; Hesiod and Apollodorus include her in the Nereid catalogues.

I.Nereid of the shore
Actaea belongs to the Hesiodic and Homeric catalogues of Nereus' daughters. In Iliad 18 she and her sisters appear when Thetis cries out in sympathy for Achilles' grief over Patroclus — a catalogue appearance rather than an independent adventure cycle.
The name Actaea was also borne by a Danaid (daughter of Danaus and Pieria) and by the former name of Attica under King Actaeus; those are distinct figures.
II.Homonym care
The atlas id actaea is the Nereid alone. The Danaid Actaea is actaea-danaid; Attic Actaeus/Actaea as a place-name tradition is not this node.
