The Huma River is a right tributary on the northern loop of the Amur River in China's province of Heilongjiang. It starts in the Greater Khingan Mountains and flows in a general eastern and south-eastern direction, parallel and southwest of the Amur, until flowing into the Amur in Huma County, about 10 km (6 mi) south of Huma County's county seat.[1]
Somewhere near its mouth was the Russian fort of Kumarsk at the time of the Russian–Manchu border conflicts. At the time it was also called "Kamora River" or "Houmar River".
