Xenoceratops (meaning "alien horned face") is a genus of centrosaurine ceratopsid dinosaur known from the Late Cretaceous (middle Campanian stage), and is known to have lived in what is currently Alberta, Canada.

[2] The formation is very poorly understood in regards to dinosaur fauna;[1] aside from teeth, only hadrosaur skeletons and the pachycephalosaurid Colepiocephale have been reported.

This is a skull bone that in ceratopsids makes up the medial (midline) and part of the lateral borders of the distinctive bony frill.

Another fragmentary skull in the collections of the Royal Tyrrell Museum of Palaeontology is thought to belong to this genus as well.
