Kherlen River (also known as Kern or Kerülen; Mongolian: Хэрлэн гол; Chinese: 克鲁伦河; pinyin: Kèlǔlún hé) is a 1,254 km river in Mongolia and China.[1]


The river originates in the south slopes of the Khentii mountains, near the Burkhan Khaldun mountain in the Khan Khentii Strictly Protected Area, about 180 kilometres or 112 miles northeast of Ulaanbaatar.[1] This area constitutes the divide between the Arctic (Tuul River) and Pacific (Kherlen, Onon) basins and is consequently named “Three River Basins”.

From there the Kherlen flows in a mostly eastern direction through the Khentii aimag. On its further way it crosses the eastern Mongolian steppe past Ulaan Ereg and Choibalsan, entering China at 48°3′N 115°36′E / 48.050°N 115.600°E / 48.050; 115.600 and emptying into Hulun Nuur after another 164 kilometres or 102 miles.


In years with high precipitation, the normally exitless Hulun Lake may overflow at its northern shore, and the water will meet the Ergune River after about 30 kilometres or 19 miles.[1] The Ergune marks the border between Russia and China for about 944 kilometres or 587 miles, until it meets the Amur River. The system Kherlen-Ergune-Amur has a total length of 5,052 kilometres or 3,139 miles.
