Gryposaurus (meaning “hooked-nosed (Greek grypos) lizard”; sometimes incorrectly translated as “griffin (Latin gryphus) lizard”) was a genus of duckbilled dinosaur that lived about 80 to 75 million years ago, in the Late Cretaceous (late Santonian to late Campanian stages) of North America. Named species of Gryposaurus are known from the Dinosaur Park Formation in Alberta, Canada, and two formations in the United States: the Lower Two Medicine Formation in Montana and the Kaiparowits Formation of Utah. A possible additional species from the Javelina Formation in Texas may extend the temporal range of the genus to 66 million years ago.

Gryposaurus is similar to Kritosaurus, and for many years the two were thought to be synonyms.
