Britomartis was a Greek goddess of mountains and hunting, who was primarily worshipped on the island of Crete. She was sometimes believed to be an oread, or a mountain nymph, but she was often conflated or syncretized with Artemis and Aphaea, the "invisible" patroness of Aegina. She is also known as Dictynna or as a daughter of Dictynna (Δίκτυννα).

In Greek mythology, an Oread or Orestiad is a mountain nymph. Oreads differ from each other according to their dwelling: the Idaeae were from Mount Ida, Peliades from Mount Pelion, etc. Myths associated the Oreads with Artemis, since the goddess, when she went out hunting, preferred mountains and rocky precipices.
