Heishui Mohe

The Heishui or Blackriver Mohe (Chinese: ; pinyin: Hēishuǐ Mòhé; Jurchen: Sahaliyan i Aiman or ), also known as the Heuksu Malgal, were a tribe of the Mohe people in Outer Manchuria along the Amur River (Chinese: ; pinyin: Hēi Shuǐ; literally: "Blackwater" or "Black River") in what is now Russia's Khabarovsk, Amur, and Jewish Provinces and China's Heilongjiang Province.

The southern Blackriver Mohe were subjects of King Seon of the Korean state of Balhae. Balhae was conquered by the Khitan Liao Empire in AD 926.

The Blackriver Mohe are sometimes linked with the Jurchen who established China's Jin Dynasty in the 10th century and who later formed the core of the Manchu who established the Qing Dynasty in the 17th century. At the time of their notice by Chinese historians, the Jurchen inhabited the forests and river valleys of the land which is now divided between China's Heilongjiang Province and Russia's Maritime Province, outside the range of the Blackriver Mohe, and such links remain conjectural.
