Agujaceratops (meaning "Horned face from Aguja") 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 Texas. Originally known as Chasmosaurus mariscalensis and described by Lehman in 1989, it was moved to a new genus by Lucas, Sullivan and Hunt in 2006. Lehman felt the habitat Agujaceratops lived in (at least where the fossil material was found) may have been a swamp, due to the nature of the sediments. Lehman, Wick & Barnes (2016) described a second species, Agujaceratops mavericus.
