==Geography==
{{Unreferenced section|date=August 2022}}
Heilongjiang is a land of varied topographies. Much of the province is dominated by mountain ranges such as the [[Greater Khingan]] Range and [[Lesser Khingan]] Range, [[Zhangguangcai Mountains]], [[Laoye Mountains]], and [[Wanda Mountains]]. The highest peak is [[Datudingzi Mountain]] at {{convert|1690|m}}, located on the border with [[Jilin]] province. The Greater Khingan Range contains China's largest remaining virgin forest and is an important area for China's forestry industry.

The east and southwest of the province, which are relatively flat and low in altitude, feature the [[Muling River]], the [[Naoli River]], the [[Songhua River]], the [[Nen River]], and the [[Mudan River]], all tributaries of the Amur, while the northern border forms part of the Amur valley. [[Xingkai Lake]] (or [[Khanka Lake]]) is found on the border with [[Russia]]'s [[Primorsky Krai]].
