In Greek mythology and, later, Roman mythology, the Oceanids (/, /; Ancient Greek: Ὠκεανίδες, pl. of Ὠκεανίς) are sea nymphs who were the three thousand daughters of the Titans Oceanus and Tethys. Each was the patroness of a particular spring, river, sea, lake, pond, pasture, flower or cloud. Some of them, such as Clymene, Asia, and Electra, were closely associated with the Titan gods or personified abstract concepts (Tyche, Peitho).
Oceanus and Tethys also had 3,000 sons, the river-gods Potamoi (Ποταμοί, "rivers"). Whereas most sources limit the term Oceanids or Oceanides to the daughters, others include both the sons and daughters under this term.
Notable Oceanids include:
- Clymene, the wife of Iapetus, and mother of Atlas, Menoetius, Prometheus, and Epimetheus.
- Electra, wife of Thaumas and mother of Iris and the Harpies
- Styx, goddess of the river Styx, and the wife of Pallas and mother of Zelus, Nike, Kratos, and Bia.
