In Greek mythology, Cymodoce (Ancient Greek Κυμοδόκη, "wave-gatherer") is one of the fifty Nereids, daughters of Nereus and Doris. Hesiod credits her, with Cymatolege and Amphitrite, with calming waves and raging winds; Homer names her among Thetis' mourning sisters.

I.Wave-calming Nereid
Hesiod (Theogony 252–254) gives Cymodoce her distinguishing deed in the catalogue itself: with Cymatolege and Amphitrite she easily calms the waves upon the misty sea and the blasts of raging winds. Homer lists her in the bright cave when Thetis gathers her sisters to mourn Patroclus (Iliad 18.39–51). Hyginus repeats her among Nereus' daughters.
Later poets place her in Cyrene's train (Virgil, Georgics) and among Nereids who aid Aeneas in a storm (Aeneid 5). Virgil also reuses the name for one of Cybele's ship-nymphs transformed from Aeneas' burning pine hulls — a Roman doublet, not the Hesiodic Nereid of this atlas node.
II.Homonym care
The atlas id cymodoce with kinds nereid is the daughter of Nereus alone. Distinct from Virgil's transformed ship-nymph of the same name and from the crustacean genus Cymodoce.
