In Greek mythology, Crius (/ˈkraɪəs/; Ancient Greek: Κρεῖος or Κριός, Kreios/Krios) was one of the Titans, children of Uranus and Gaia. As the least individualized among the Titans, he was overthrown in the Titanomachy. M. L. West has suggested how Hesiod filled out the complement of Titans from the core group—adding three figures from the archaic tradition of Delphi, Coeus, and Phoibe, whose name Apollo assumed with the oracle, and Themis. Among possible further interpolations among the Titans was Crius, whose interest for Hesiod was as the father of Perses and grandfather of Hecate, for whom Hesiod was, according to West, an "enthusiastic evangelist".
