Arrhinoceratops was a genus of herbivorous ceratopsian dinosaurs that lived during the early Maastrichtian stage of the Late Cretaceous. The name means "noseless-faced," and its remains were found in Canada. It was known for a slightly distorted skull that lacked a lower jaw, as described by W. A. Parks in 1925. They roamed North America and Asia during the Cretaceous period about 65 million years ago.

It belonged to the Ceratopsinae within the Ceratopsia, a group of parrot-beaked herbivorous dinosaurs. It has moderately long horns on the forehead and a shorter, blunter nose compared to most ceratopsians. It has a broad, square neck with two oval-shaped openings. The rear edge of the frill is slightly scalloped, while about nine osteoderms adorn the sides of the frill.

It ate predominant plants of the time, such as ferns, cycads and conifers. It used its sharp ceratopsian beak to chew on leaves or needles.

Arrhinoceratops were estimated to be 4.5 meters long and weighed 1.3 tons.
