Pachycephalosaurus is a genus of pachycephalosaurid dinosaurs. The type species, P. wyomingensis, is the only known species, but some researchers argue that there might be a second species, P. spinifer. 

Like other pachycephalosaurids, Pachycephalosaurus was a bipedal herbivore with an extremely thick skull roof. It possessed long hindlimbs and small forelimbs.

It is the largest-known pachycephalosaur. The thick skull domes of Pachycephalosaurus and related genera gave rise to the hypothesis that pachycephalosaurs used their skulls in intra-species combat. This hypothesis has been disputed in recent years.

**Stygimoloch is a controversial genus of Pachycephalosaurid due to two studies in 2009 and 2016 which argued that both Dracorex and Stygimoloch were actually immature forms of Pachycephalosaurus as well as a corroborative 2010 study which suggested that all flat-headed Pachycephalosaurids were juveniles of dome-headed adults.
