Ligustrum expansum is a plant species native to China and Vietnam. The Flora of China lists Ligustrum robustum subsp. chinense P.S.Green as a separate taxon, but more recent sources regard this name as a synonym of L. expansum. Combining the two listings yields a distribution within China including the Provinces of Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, Sichuan, and Yunnan.
