In Greek mythology, an Oread /ˈɔːriˌæd/ or /ˈɔːri.əd/ (Ancient Greek: Ὀρειάς stem Ὀρειάδ- Oreas/Oread-, from ὄρος, "mountain") or Orestiad /ɔːˈrɛstiˌæd/ or /ɔːˈrɛsti.əd/ (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.
