In Greek mythology, an Oread (; , stem Ὀρειάδ- Oreas/Oread-, from ὄρος, mountain) or Orestiad ; Όρεστιάδες, Orestiades) is a mountain nymph. 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.
