In Greek mythology, the Oceanids or Oceanides are the nymphs who were the three thousand daughters of the Titans Oceanus and Tethys.

A nymph is a minor female nature deity in ancient Greek folklore. Distinct from other Greek goddesses, nymphs are generally regarded as personifications of nature, are typically tied to a specific place or landform, and are usually depicted as maidens. They were immortal like other goddesses, except for the Hamadryads, whose lives were bound to a specific tree.
