China has 228 rivers with drainage basins larger than 10,000 square kilometres, with a combined length of 132,500 kilometres. [1] Their annual runoff ranks 6th in the world. [2] Three of the world's ten longest rivers flow through China. [3]
Rivers in China can originate from three main regions: Southeast of Tibetan Plateau, where most longest rivers in China origined; the corridor between Da Hinggan Range, Hebei and Shanxi mountains, Western Henan mountains, and Yunnan–Guizhou Plateau - rivers here generally have relatively small discharges; and the corridor between Changbai Mountain, Shandong hills, and southeastern coastal ranges - rivers origins here are generally has shorter and smaller drainage basins than the former two, but carry abundant water.
Most rivers in China are exorheic, which flow into the Pacific Ocean, the Indian Ocean, and the Arctic Ocean. They flow into the Pacific Ocean, which occupied 56.7% of the total land. [4] The area of Greater Khingan-Yin Mountains-Helan Mountains-Eastern Qilian Mountains-Bayan Har Mountains-Gangdise Shan divide China's endorheic and exorheic regions. Rivers west of the area are mostly endorheic: While the rivers cover one-third of the country's land area, they contain less than 5% of the total water. [5]
There are seven drainage systems in China. From north to south, they are: Songhua River, Liao River, Hai River, Yellow River, Huai River, Yangtze, and Pearl River. They occupy most rivers in China. [2] 。
This list includes rivers that flow through China with main stems at least 1,000 km long. Transboundary rivers whose length within China is shorter than 1,000 km are not included. [Note 1]
The list number is based on the Encyclopedia of Rivers and Lakes in China . Numbers vary between sources due to differences in the definition of a river's source or the methods used to measure its length. [11] The list will note figures from other sources if they differ by more than 10%.
In this list, only river length, drainage areas, and discharge within China are counted. The number of rivers outside China, i.e. transboundary rivers, is given in parentheses.
indicated that parts of the river crossed Chinese boundaries (i.e. transboundary river).
China is one of the oldest civilisations constructing canals, with the oldest canal of the Beijing-Hangzhou Grand Canal. The largest water transfer scheme in the world is the South–North Water Transfer Project in China. [34]

The mean annual flow of the river at Krâchéh in Cambodia is about 500,000 cubic feet (14,200 cubic metres) per second[.]
