Nefertiti (nĕfˌərtēˈtē) [key] or Nefretete nĕfˌrĕtēˈtē, fl. c.1372–1350 B.C., queen of ancient Egypt; wife of Ikhnaton (XVIII dynasty) and aunt of Tutankhamen. She seems to have been divorced by Ikhnaton late in his reign. The exquisite limestone bust of Nefertiti (Berlin Mus.) has given rise to the tradition that she was one of the most beautiful women of antiquity.
