Cercocarpus, commonly known as mountain mahogany, is a small genus of five or six species of flowering plants in the rose family, Rosaceae. They are native to the western United States and northern Mexico, where they grow in chaparral and semi-desert habitats and climates, often at high altitudes. Several are found in the California chaparral and woodlands ecoregion.

Cercocarpus intricatus, Spring Mountains, southern Nevada (elevation about 2700 m)

The classification of Cercocarpus within the Rosaceae has been unclear.^[2][3] The genus has been placed in the subfamily Rosoideae, but is now placed in subfamily Dryadoideae.^[4]

Members of the genus are deciduous shrubs or small trees, typically reaching heights of 3 to 6 meters (9–18 feet) tall, but exceptionally up to 13 meters (40 feet) high. C. montanus usually remains under 1 meter (3 feet) high because of incessant browsing by elk and deer.

The name is derived from the Greek words κέρκος (kerkos), meaning "tail" and καρπός (karpos), meaning "fruit." It refers to the tail-like plume on the fruits.^[5]
