Cercocarpus montanus is a North American species of shrub or small tree in the family Rosaceae native to northern Mexico and the western United States. It is known by the common names alder-leaf mountain-mahogany, alder-leaf cercocarpus, and true mountain-mahogany. The variety argenteus is commonly known as silverleaf mountain-mahogany.
Cercocarpus montanus is common in chaparral scrub, on mesas, the lower foothills of the Rocky Mountains, and the Great Plains in the United States. Its range extends from Montana, Idaho, and South Dakota south as far as Sonora, Durango, and Nuevo León.
Cercocarpus montanus often remains under 1 metre (3.3 ft) in height because of browsing by elk and deer, but can reach 20 feet (6.1 m). It has thin and smooth bark. The species is considered to be long lived.
