Noasaurus (“Northwestern Argentina lizard”) is a genus of ceratosaurian theropod dinosaur genus from the late Campanian-Maastrichtian (Late Cretaceous) of Argentina. N. leali is the only and type species.

Jaime Eduardo Powell, Jose Fernando Bonaparte and the Estancia El Brate-site discovered a small fragmentary theropod skull in the middle of the Seventies. The scientific literature published the discovery in 1977. Bonaparte & Powell named the type species Noasaurus leali in 1980. The generic name starts with an abbreviation for noroeste Argentina, which is “northwest Argentina”. Fidel Leal, the site’s owner, is the specific name.

The holotype PVL 4061 was found in the Lecho Formation, Salta Province, Argentina. It dates back to the late Cretaceous period and more specifically the early Maastrichtian stage. This is approximately seventy-million years ago. It is composed of a partial skull and skeleton. It includes the maxilla and quadrate bones, as well as two neck vertebrae and two neck ribs. Initial identification of one of the hand claws as a second-toe claw was incorrect. It was later identified as a hand claw in 2004. At that time, the second hand claw was also referred to.

A neck vertebra, specimen MACM622, was found at the site in 1999. It was identified as an oviraptorosaurian. This is a rare evidence that Oviraptorosauria invaded Gondwanan continents. It was identified as a noasaurid verbra in 2007, probably belonging to Noasaurus.
