Snub-nosed monkeys are a group of Old World monkeys and make up the entirety of the genus Rhinopithecus. The genus occurs rarely and needs much more research. Some taxonomists group snub-nosed monkeys together with the Pygathrix genus.

Snub-nosed monkeys live in Asia, with a range covering southern China (especially *****, Sichuan, Yunnan, and Guizhou) as well as the northern parts of Vietnam and Myanmar.
