In Greek mythology, Ligeia or Ligia ( from ligeios) may refer to two personages:
Ligea, one of the 50 Nereids, sea-nymph daughters of the Old Man of the Sea, Nereus and the OceanidDoris. She was one of the nymphs in the train of Cyrene. Ligeia was described to have bright, waving locks of hair and a slender pale neck.
