Hulun Lake (simplified Chinese: 呼伦湖; traditional Chinese: 呼倫湖; pinyin: Hūlún Hú; Mongolian: hölön nuur Хөлөн нуур, lit. foot lake) or Dalai Lake (Mongolian: Dalai nuur Далай нуур, lit. ocean lake), is a lake in Inner Mongolia, China. It is one of the five largest freshwater lakes in all of China, covering approximately 2,339 km².

As in 1995 annual fish production was about 7,000 tons, 100 tons of shrimp, 4 kilograms of pearls, 1.5 million crayfish. The lake is also one of the key reed production areas in China.

It is a tourist destination during the summer, but during off times, the lake's visitors are few. The lake is not far from Manzhouli, which is on a major rail-line. Although there are several villages nearby, Manzhouli is the nearest city of reputable size.
