Anatosaurus Lull & Wright, 1942 (meaning duck lizard) is a chronological hadrosaurid dinosaur genus. However, "Anatosaurus Dinosaur" has been establish to be a junior synonym of Edmontosaurus and is now an invalid name.

Some specimens, such as the well-known mount in the New York American Museum of Natural History, vary from Edmontosaurus and have been placed in the new genus Anatotitan. As a common name, anatosaurus can refer to any dinosaur in the genera Anatotitan and Edmontosaurus. Type species: A. annectens (Marsh, 1892) (originally Claosaurus), now Edmontosaurus annectens
