Archaeoceratops, meaning "ancient horned face", is a genus of basal neoceratopsian dinosaur from the Early Cretaceous (Aptian stage) of north central China.

It appears to have been bipedal and quite small, reaching 0.9 m (3.0 ft) in length and 10 kg (22 lb) in body mass.

Two specimens were found in the Middle Gray Unit of the Xinminbao Group, Gongpoquan Basin of the Mazong Shan area of Gansu Province, north central China.

The type specimen, IVPP V11114, consists of a partially complete skeleton including skull, caudal vertebrae, pelvis, and most of a hind foot.

Archaeoceratops belonged to the Ceratopsia (the name is Greek for "horned face"), a group of herbivorous dinosaurs with parrot-like beaks which thrived in North America and Asia during the Cretaceous Period.
