Jingpo Lake or Lake Jingpo (Chinese: 镜泊湖; Pinyin: Jìng Pō Hú) is a lake located in the upper reaches of the Mudan River among the Wanda Mountains in Ningan County, Heilongjiang Province, in the People's Republic of China. Earlier names for the lake include Meituohu Lake (湄沱湖), Huhanhai Lake (忽汗海), and Bilten Lake (Manchurian: ᠪᡳᠯᡨᡝᠨ; Chinese: 畢爾騰湖).

The length of the lake from north to south is 45 kilometers (28 mi) and the widest distance between east and west is only 6 kilometers (3.7 mi). The area is 95 km (37 sq mi) and the storage capacity is 1.63 billion m. The south part of lake is shallow with the deepest place in the northern part at 62 meters (203 ft).

The winter average temperature in Heilongjiang Province is below -20°C (-4°F), but the temperature at the bottom of the water is always above 10°C (50°F).

On Titan, the largest moon of the planet Saturn, there is a large surface body of liquid hydrocarbons, Jingpo Lacus, named after Jingpo Lake.

The lake was created about 10,000 years ago when the lava of volcanic eruptions in the region blocked the flow of the Mudan River. Jingpo Lake has experienced five volcanic eruptions. It is the largest alpine lava barrier lake in China.
