The Argun or Ergune is a 1,621 kilometres (1,007 mi) river that forms part of the eastern China–Russia border, together with the Amur River (Heilong Jiang). Its upper reaches are known as Hailar River (Chinese: 海拉尔河; pinyin: Hăilā'ěr Hé) in China. The Ergune marks the border (established by the Treaty of Nerchinsk in 1689) between Russia and China for about 944 kilometres (587 mi), until it meets the Amur River.

The name derives from Buryat Urgengol 'wide river' (urgen 'wide' + gol 'river').Mongolian word "ergün" (in Traditional Mongolian alphabet) or "örgön" (in modern Mongolian) means "wide".

The river flows from the Western slope of the Greater Xing'an Range in China's Inner Mongolia, and forms the Chinese side of the two rivers that flow together to produce the Amur (Heilong). Its confluence with the Shilka River at Ust-Strelka on the Russian side forms the Amur River.

In years with high precipitation, the normally exitless Hulun Lake may overflow at its northern shore, and the water will meet the Ergune after about 30 kilometres (19 mi). The Kherlen–Ergune–Amur system has a total length of 5,052 kilometres (3,139 mi).

In The Secret History of the Mongols is a legend related to the Ergüne hun Mongol ancestry. In this legend, the Mongols prevailed over other tribes and carried such slaughter among them, that in living remained no more than two men and two women. These two families, in fear of the enemy, fled to the inhospitable terrain, which included only mountains and forests and to which there was no road. Among those mountains was the abundant grass and healthy climate of the steppe. Then, legend tells that in Ergune-Khun, Mongols multiplied and become masters of iron smelting and blacksmithing. According to legend, it is the art of melting iron that has helped them escape from the mountain gorges on scope of the current Mongolian steppes, to the Kherlen (Kelulun) and Onon River.
