In Greek mythology, Orphne (/ˈɔːrfniː/; Ancient Greek: Ὀρφνή, romanized: Orphnḗ, from ὄρφνη, órphnē, 'darkness') was a nymph that lived in Hades. She was also known as Styx (/ˈstɪks/; Στύξ, Stýx) or Gorgyra (/ɡɔːrˈdʒaɪrə/; Γόργυρα, Górgȳra, from γόργυρα, górgȳra, 'underground drain').^[1] With Acheron, she mothered Ascalaphus.^[2]

Orphne also seems to be one translation of the name of the Roman goddess Caligo (Darkness).^[3]
