Stygimoloch is a type of pachycephalasaur that lived in North America during the late Cretaceous. It was a large pachycephalasaur, with only Pachycephalasaurus being larger.

Unlike other pachycephalasaurs, its dome was small, and flattened from the sides, however, it had more ornamentation on its dome than other pachycephalasaurs. It had short conical hornlets on the nose, and large backwards pointing spikes on its head. The function of these spikes is unknown, but they might have been used to attract mates.

In 1995, a complete skeleton of this dinosaur was discovered, making it the first complete pachycephalasaur skeleton.
