Agujaceratops is a genus of horned dinosaur from the Late Cretaceous of west Texas. It is a chasmosaurine ceratopsian. Two species are known, Agujaceratops mariscalensis, and A. mavericus. 

All specimens of Agujaceratops were collected from the lower part of the Upper Shale member of the Aguja Formation, dating to about 77 million years ago,[2] in the Big Bend National Park, Brewster County. Additional material was recovered from elsewhere in west Texas, including a nearly complete skull from Rattlesnake Creek.
