Rhus chinensis, the Chinese sumac or nutgall tree, is a plant species in the genus Rhus.

The species is used to produce galls, called Chinese gall, Galla Chinensis or Wu Bei Zi (五倍子) in Chinese, which are rich in gallotannins, a type of hydrolysable tannins. The infestation by Chinese sumac aphids (Melaphis chinensis Bell) can lead to a gall which is valued as a commercial product. Chinese galls are used in Chinese medicine to treat coughs, diarrhea, night sweats, dysentery and to stop intestinal and uterine bleeding.
