The Yorungqash or White Jade River, also spelt Yorungkax (Chinese: 白玉河; pinyin: Báiyù Hé), is a river in the southern Xinjiang region, People's Republic of China.
The head waters of the river rise in the Kunlun Mountains, in the Togatax area (). The river flows east for some 200 km and then north for another 200 km before passing Khotan (). North of Khotan, it eventually dries up in the Taklamakan desert, its seasonal bed joined by that of the Karakash River near Koxlax (some 200 km north of Khotan, ), from where it continues north as the Khotan River passing Piqanlik (), and seasonally crossing the desert, joining the Tarim River at . The river drains an area of 14,575 km2 (5,627 sq mi) and has a discharge of 72.3 cubic metres per second (2,550 cu ft/s).
The river gets its name from the white jade that is often found in its alluvial deposits.
