Noasaurus ("Northwestern Argentina lizard") is the name given to a carnivorous dinosaur genus of the late Campanian-Maastrichtian (Late Cretaceous). It was a small (less than eight feet long) theropod, specifically a ceratosaur, discovered by Jaime Powell and José Bonaparte from the Lecho Formation of Salta Province, Argentina, dating to the late Cretaceous period (early Maastrichtian stage, about 70 Ma ago).

It was a close relative of the larger abelisaurids; they are both derived from the same basal abelisauroid ancestor. While originally reported to have a raptorial 'sickle claw' on the foot similar to the claws of the more advanced dromaeosaurids, subsequent studies showed that the claw actually came from the hand.[1]

The type species, Noasaurus leali, was described by Bonaparte and Powell in 1980.
