Huangpu, Whangpoo, or Hwangpoo (all: hwäng´pōō´), river, 60 mi (97 km) long, rising in the lake district of Shanghai Municipality, E China, and flowing NE past Shanghai into the Chang estuary at Wusong. It is a major navigational route. Its dredged channel, lined with wharves, warehouses, and industrial plants, provides access to Shanghai for oceangoing vessels. The river is also a major water source for Shanghai, and as the city has grown it has suffered from water shortages and polluted drinking water; in 1996 a project to divert water from the Chang River (Yangtze) to the Huangpu was completed.
