In Greek mythology and, later, Roman mythology, the Oceanids (/oʊˈsiːənɪdz, ˈoʊʃᵊnɪdz/; 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, Electra/Ozomene, were closely associated with the Titan gods or personified abstract concepts (Tyche, Peitho).
