The Dangqu River (Chinese: 当曲, Dāngqū) or Dam Chu (Tibetan: འདམ་ཆུ, 'Dam Chu, "Marshy River") is a river in Qinghai province in the People's Republic of China. It is the geographic headwater of the Yangtze River, although the PRC officially recognizes the nearby Ulan Moron as the source.
The Dangqu runs from its source in the Tanggula Mountains (唐古拉山) to its confluence with the Ulan Moron, which forms the Tongtian River.
