An underground lake or a subterranean lake is a lake under the surface of the Earth. Such a lake may be associated with caves, aquifers, or springs. They are typically very low in salinity.

The largest non-subglacial underground lake in the world is Dragon's Breath Cave, Namibia, with an area of almost 2 hectares (5 acres)[1] and the second largest is Craighead Caverns in Tennessee, United States of America.
