Atrociraptor marshalli ("Marshall's cruel thief") is a dromaeosaurid dinosaur species from the Upper Cretaceous (Upper Maastrichtian) of Alberta, Canada. The type (and only) specimen was discovered in the Horseshoe Canyon Formation, near Drumheller, Alberta. It had a relatively short, massive skull with slender lower jaws and long, highly curved teeth (the rest of the skeleton is unknown). Similar teeth are found in the Upper Cretaceous Lance Formation. Atrociraptor seems to be most similar to Deinonychus.
