Which lake is shared by Switzerland and France and is also called Lac Léman?

Lake Geneva is shared by Switzerland and France and is also called Lac Léman.

The crescent-shaped lake lies on the Rhône River, with most of its surface in Switzerland and a smaller southwestern section in France. Geneva sits at its western outlet, where the Rhône continues toward France and eventually the Mediterranean Sea.

The lake is known internationally as Lake Geneva, while French usage commonly calls it Lac Léman. This difference can create confusion even though both names refer to the same body of water. Lausanne and Montreux are among the other notable Swiss lakeside cities.

Lake Geneva is one of western Europe’s largest lakes and is surrounded by the Alps and Jura Mountains. Its deep blue scenery has made the shoreline an important destination for tourism, science and international institutions.
