Menefeeceratops is a genus of ceratopsid dinosaur from the Menefee Formation in the United States. It is is believed to have been approximately 4 m long, and had two large horns above the eyes like other ceratopsians. Menefeeceratops was one of the earliest and most basal known members of the ceratopsids, and the oldest known centrosaurine. Its age and location was instrumental in helping to understand the evolution and diversification of the centrosaurine dinosaurs.
