Keteleeria fortunei is a conifer native to Southeast Asia (Hong Kong and China) and present in China (Fujian, Guangdong, Guangxi, Guizhou, Hunan, Jiangxi, Yunnan, Zhejiang), Hong Kong and Vietnam; however the report in Vietnam is attributed to an incorrect identification of immature specimens of Pseudotsuga sinensis.
Its habitat in southern China is that of the mountains near Fuzhou, where it was seen and determined by Fortune in 1844, who propagated its seeds and where it grows in hills, mountains and deciduous forests at altitudes of 200–1400 m.
