Allium thunbergii is a plant species native to Japan, Korea and parts of China (Hebei, Heilongjiang, Henan, Hubei, Jiangsu, Jilin, Liaoning, Nei Mongol, Shaanxi, Shandong, Shanxi, Taiwan). It grows at elevations up to 3000 m. The Flora of China recognizes A. tunbergii and A. stenodon as separate species, but more recent sources combine the two.
