Keteleeria fortunei (zh: 油杉, you shan) is a coniferous evergreen tree native to Hong Kong and China in the provinces of Fujian, Guangdong, Guangxi, Guizhou, Hunan, Jiangxi, Yunnan, and Zhejiang. The tree grows in hills, mountains, and broadleaf forests at elevations of 200–1400 m. The species is named after Scottish botanist Robert Fortune, who discovered the tree in 1844. The tree is grown as an ornamental in warm climates, and the wood is used in construction and furniture, although the species is protected under Chinese forestry regulations.
