The Albertaceratops (meaning “Alberta horned face”) was a genus belonging to centrosaurine horned dinosaurs of the middle campanian age Upper Cretaceous Oldman Formation of Alberta, Canada.

Albertaceratops is unique in that it combines long brow horns and the skull of a centrosaurine because centrosaurines usually have small eyebrow hairs. On its face is a bone ridge and on its frill , two hooks that project outwards. The length of the piece has been estimated to be 5.8 meters (19 feet) and 3,500 kg (7,700 pounds).

Albertaceratops is recognized by a single, complete skull (TMP.2001.26.1) discovered in August 2001, as well as postcranial and skull fragments. A phylogenetic study conducted by its author, Michael J. Ryan discovered this to be one of the basal centrosaurine. Additional specimens were found from a bone bed in the Judith River Formation of Montana that is similar with the Oldman Formation, and is distinguished only by the Canadian-US border. But further research revealed the remains belonged to another centrosaurine called Medusaceratops. Both ceratopsids were alive in the same time frame approximately 77.5 million years ago.
