Cyanocorax is a genus of New World jays in the Corvidae family. The generic name is derived from the Greek words κυανος (kuanos), meaning "dark blue," and κοραξ (korax), meaning "raven". It contains several closely related species that primarily are found in wooded habitats of Mexico and Central and South America, with the green jay just barely entering the United States. Coincidentally, it is also the only species in this genus where the upperparts are not primarily blue or purplish.
