Ojoraptorsaurus is a genus of oviraptosaur that lived in what is now New Mexico during the earlier stage of the Maastrichtian. Although only named from fossilised pubis bones, Ojoraptorsaurus has been identified as a caenagnathid oviraptosaur, making it a closer relative to genera such as Elmisaurus and Gigantoraptor. With the holotype fossils of Ojoraptorsaurus coming from the Ojo Alamo Formation, Ojoraptorsaurus may well have encountered other dinosaurs such as hadrosaurs, tyrannosaurs and also ceratopsian dinosaurs such as Ojoceratops, the latter of which should not be confused with Ojoraptorsaurus.
