List of mountain lakes of Switzerland

This is a list of high-altitude lakes of Switzerland. It includes all significant lakes located either entirely or partly in Switzerland, both natural and artificial, with an area of at least 4 ha (9.9 acres) and a location at over 800 m above sea level. This altitude approximately corresponds to the transition between the foothill zone and the montane zone in both the Alps and the Jura Mountains, the two mountainous areas of Switzerland.

Lakes can be found up to elevations of almost 3000 m, the climatic snow line in the Alps. For each lake, the culminating point of the drainage basin is indicated, along with the river basin of which it is part.
