Tsona Chu or Cona Qu (Tibetan: མཚོ་སྣ་ཆུ, Wylie: mtsho sna chu, THL: tso na chu) is a cross-border river that originates in the Tsona County, Shannan Prefecture of the Tibet region of China and flows into the Arunachal Pradesh state of India, where it joins the Tawang Chu river. The name "Tawang Chu" applies to the combined river obtained by the merger of Tsona Chu with Mago Chu, the latter rising within the Tawang district in Arunachal Pradesh.
Tsona Chu enters the Tawang district near an area called Yangtse, which contains the spectacular Chumi Gyatse Falls falling from a cliff face to the east. The China–India border in this area has been disputed between the two countries since the 1990s.
