In Greek mythology, Crius (/ˈkraɪəs/; Ancient Greek: Κρεῖος or Κριός, Kreios/Krios) was one of the Titans, children of Uranus and Gaia. Like other Titans, Crius lacks much characterization, with no unique domain or mythology of his own, instead apparently serving a purely genealogical function in mythology, to provide parentage for other figures.
