Sinoceratops /ˌsaɪnoʊˈsɛrətɒps/ is an extinct genus of ceratopsian dinosaur that lived from 73.5 to 66 million years ago during the latter part of the Cretaceous Period in what is now Shandong province in China.

The name of its type species Sinoceratops zhuchengensis means "Chinese horned face from Zhucheng", after the location of its discovery.

The holotype specimen ZCDM V0010, consisting of a partial skull, including a braincase, was in the summer of 2008 recovered at the Hongtuya Formation of the Wangshi Group in Shandong, China.

[1][2] The specimen was collected in fluvial sediments that were deposited during the Campanian-Maastrichtian stages of the Cretaceous period, approximately 72–66 million years ago.

Inside this row of hornlets there is a series of low knobs on the top of the frill, which are not seen in any other horned dinosaur.

[6] According to Xu et al. (2010), Sinoceratops can be distinguished based on the following diagnostic characteristics: there are at least ten robust, strongly curved hornlike processes along the rear margin of the combined parietals, while at the same time at least four hornlike processes on the combined squamosals are present; there is a large accessory fenestra in front of the antorbital fenestra (differing from all other known centrosaurines); the external margin of the parietals is only weakly undulating (differing from all other known centrosaurines); and the presence of broad-based epoccipitals (differing from all other known centrosaurines).

[1] Sinoceratops was assigned to the taxon Centrosaurinae, as a basal member by Xu et al. (2010) based on characteristics present in the skull.
