The western mountain coati or western dwarf coati (Nasuella olivacea) is a small procyonid, found in cloud forest and páramo at altitudes of 1,300–4,250 metres in the Andes of Colombia and Ecuador. A population discovered in the Apurímac–Cuzco region of southern Peru (more than 1,000 km or 620 mi south of the previous distribution limit) has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.
