Bagaceratopidae is a family of neoceratopsian dinosaurs. It was named by Alifanov in 2003 but no definition has been proposed. Because of lacking of the definition, Bagaceratopidae was considered inactive by Paul Sereno in 2005. Alifanov in 2003 classified to this family four genera: Bagaceratops, Breviceratops, Lamaceratops and Platyceratops and in a publication from 2008 he included in Bagaceratopidae also Magnirostris and newly described genus Gobiceratops. Alifanov suggested also that Bagaceratopidae, unlike other neoceratopsian families, is of Paleoasiatic origin.

Bagaceratopids existed during the late Cretaceous period, between about 85.8 and 70.6 million years ago.
