Parapapio is a genus of prehistoric baboons closely resembling the forest-dwelling mangabeys. Parapapio is distinguished from other Papio by the lack of an anteorbital drop, thin browridges, absence of maxillary fossae or a sagittal crest and only slight sexual dimorphism.

There are four recognized species, Pp. jonesi, Pp. whitei, Pp. broomi, and Pp. lothagamensis, but these taxonomic designations have generated some controversy. Traditionally, these species have been distinguished based on molar size with Pp. jonesi being the smallest and Pp. whitei the largest. However, variation in molar size in Pp. broomi overlaps the other two. Pp. jonesi is distinguished as having a more squarish muzzle than Pp. whitei but more rounded than Pp. broomi; however these distinctions are subtle and better diagnostic criteria are needed.
