From Russian Амур (Amur) of unknown origin, but most likely meaning "black river" or "black dragon," judging from Manchu sahaliyan ula "black river," Mongolian Хара-Мурэн (Khara-Muren) "black river," and Chinese 黑龍江 (heilong jiang) "black dragon river," hence the likely calques. The second syllable mur may be cognate with Mongolian muren "river," Korean 물 (mur or mul) "water, river," obsolete Korean 미르 (mireu) "dragon," etc. (Wiktionary)
