Coahuilaceratops (meaning "Coahuila horn face") is a genus of herbivorous ceratopsian dinosaur. It is a chasmosaurine ceratopsian which lived during the Late Cretaceous period (late Campanian stage) in what is now southern Coahuila in northern Mexico. It is known from the holotype CPC 276, a partial skeleton of an adult individual which includes several skull elements. Another specimen, CPS 277, may represent a juvenile Coahuilaceratops. All specimens of Coahuilaceratops were collected from a single location in the middle strata of the Cerro del Pueblo Formation, which dates to between 72.5 and 71.4 million years ago.
