Mountain coatis are two species of procyonid mammals from the genus Nasuella. Unlike the larger coatis from the genus Nasua, mountain coatis only weigh 1–1.5 kilograms (2.2–3.3 lb) and are endemic to the north Andean highlands in South America. Until recently only a single species with three subspecies was recognized. In 2009 this species was split into two species, the eastern mountain coati (N. meridensis) from Venezuela, and the western mountain coati (N. olivacea, with subspecies quitensis) from Colombia and Ecuador.
