The Nandu River (Chinese: 南渡江) is the longest river in Hainan Province, China. Its tributary is the Xinwu River. The river discharges into the Nandu River estuary at Haikou city, and then into Qiongzhou Strait.
The river is 314 km long, with a discharge of 6.099 billion cubic metres. It passes the major settlements of Chengmai Zhen in Chengmai County then Dingcheng in Ding'an County. The river then turns north, goes over the dam at Longtang, a somewhat smaller town than Chengmai and Ding'an. The Nandu then goes under several bridges, such as the Nandu River Iron Bridge and Qiongzhou Bridge. Once passed the Qiongzhou Bridge, it splits around Xinbu Island, and discharges into the Qiongzhou Strait.
From Chengmai Zhen in Chengmai County at the west to its mouth at Haikou there are numerous bridges crossing the Nandu River. Some are semi-permanent and get washed out during times of high water, while other, major bridges are currently under construction.
