The yellow baboon (Papio cynocephalus) is a baboon in the family of old World monkeys. The species epithet literally means "dog-head" in Greek, due to the shape of its muzzle and head. It has a slim body with long arms and legs and a yellowish-brown hair. It resembles the Chacma baboon, but is smaller and its muzzle is not as elongated. The hairless face is black, framed with white sideburns. Males can grow to about 84 cm, females to about 60 cm.
