In Greek mythology, an Oread or (, Oreades, from ὄρος, "mountain") or Orestiad or (Όρεστιάδες, Orestiades) was a type of nymph that lived in mountains, valleys, and ravines. They differ from each other according to their dwelling: the Idaeae were from Mount Ida, Peliades from Mount Pelion, etc. They were associated with Artemis, since the goddess, when she went out hunting, preferred mountains and rocky precipices.
