This is a list of high-altitude lakes in Switzerland. It includes all significant lakes, natural or artificial, with an area over 4 hectares and a height over 800 metres above sea level. This height approximately corresponds to the transition between the foothill zone and the montane zone, in the Alps and in the Jura Mountains. Lakes can be found up to elevations of almost 3000 metres, where is 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.
