The Rhône (; ; ; Walliser German: Rotten ; ; ; ) is one of the major rivers of Europe, rising in Switzerland, passing through Lake Geneva and running through southeastern France. At Arles, near its mouth on the Mediterranean Sea, the river divides into two branches, known as the Great Rhône (French: Le Grand Rhône) and the Little Rhône (Le Petit Rhône). The resulting delta constitutes the Camargue region.
