'''Mountain-mahogany''' (''Cercocarpus'') is a small genus of five or six species of [[deciduous]] [[shrub]]s or small [[tree]]s in the rose family ([[Rosaceae]]), native to the western [[United States]] and northern [[Mexico]], where they grow in semi-[[desert]] climates, often at high altitudes. They typically reach 3–6 m tall, but exceptionally up to 13 m tall.

The classification of ''Cercocarpus'' within the Rosaceae is presently unclear. The genus was originally placed in the subfamily [[Rosoideae]], and later in subfamily [[Dryadeae]] along with the genera ''[[Chamaebatia]]'', ''[[Purshia]]'' and ''[[Dryas (plant)|''Dryas'']]'', all four genera sharing [[root nodule]]s that host the [[nitrogen fixation|nitrogen-fixing]] [[bacterium]] ''[[Frankia]]''. However, recent genetic research indicates that Dryadeae may be polyphyletic, with ''Dryas'' not closely related to the other three genera. <br clear = left>
