The Argun or Ergune (Russian: Аргунь, Buryat: Эргэнэ гол, Ergene gol; Mongolian: Эргүнэ мөрөн, Ergüne mörön; Evenki: Ергэне Yergenye, Chinese: 额尔古纳河 Éěrgǔnà hé) is a 1,620-kilometre (1,010 mi) long river that forms part of the eastern China–Russia border, together with the Amur (Heilong Jiang). Its upper reaches are known as Hailar River (Chinese: 海拉尔河; pinyin: Hǎilā'ěr Hé) in China. The Argun 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.
