Amtocephale (meaning "Amtgai head") is a genus of pachycephalosaurid dinosaur from early Late Cretaceous (Turonian-Santonian stages) deposits of southern Gobi Desert, Mongolia. Amtocephale is known from the holotype MPC-D 100/1203, a nearly complete frontoparietal dome of a subadult individual. It was collected from the Baynshire Formation at the Amtgai locality. Amtocephale was first named by Mahito Watabe, Khishigjaw Tsogtbaatar and Robert M. Sullivan in 2011 and the type species is Amtocephale gobiensis. The generic name combines a reference to the Amtgai site with a Greek κεφαλή, kephale, "head". The specific name refers to the provenance from the Gobi.
