Ceratotherium mauritanicum is a species of fossil African rhinoceros found in the Late Pliocene to earliest Holocene of Morocco, Tunisia, and Algeria. Slightly older fossils from the Pliocene of eastern Africa were also proposed to belong to this species, but it has been considered to belong to a somewhat more primitive species, Ceratotherium efficax. A 2020 study considers C. efficax to be the same species as C. mauritanicum, however.
