Castanopsis sclerophylla (syn. Lithocarpus chinensis), the Chinese tanbark-oak, is a species of flowering plant in the family Fagaceae, native to southern China. In the wild it is typically found growing in broad-leaved evergreen forests at above sea level. It is an evergreen tree with glossy, thick leaves and attractive flaky bark, and reaches in height.
The small nuts are edible, and the Chinese process them into a foodstuff similar to tofu. It is used as a street tree in a number of Chinese cities. Hardy to USDA zone 7b, it does well in the southeastern United States, and is offered by several nurseries there under its synonym Lithocarpus chinensis.
