The Yalong River is an 1,323 km long river in Sichuan Province in southwestern China. It is a tributary of the Yangtze River. Its source originates from the Tibet-Qinghai Plateau in southeast Qinghai, and its confluence with the Yangtze is in Panzhihua in southwestern Sichuan.
The Yalong RIver rises in the Bayan Har Mountain in southern Qinghai Province at an elevation of nearly 5,000 meters. The upper stream flows southeastward from the Bayan Har Mountains into northeastern Sichuan Province. Below Ganzi, it swings southward to flow along the western side of the Daxue Mountains. After making some wide loops in its course at the southern end of these mountains, the river flows into the Jinsha River.
