The Rhône ( , ; wae, Rotten ; frp, Rôno ; oc, Ròse ) is a major river in France and Switzerland, rising in the Alps and flowing west and south through Lake Geneva and southeastern France before discharging into the Mediterranean Sea. At Arles, near its mouth, the river divides into the Great Rhône (french: le Grand Rhône, links=no) and the Little Rhône (). The resulting delta forms the Camargue region.

The Rhône is infamous for its strong current when the river carries large quantities of water: current speeds up to are sometimes reached, particularly in the stretch below the last lock at Vallabrègues and in the relatively narrow first diversion canal south of Lyon.

As a result, the Rhône Valley experiences a drier climate than the rest of Switzerland, being sheltered by the three highest ranges of the Alps, making Valais the driest and largest wine region of the country.
At Martigny, where it receives the waters of the Drance on its left bank, the Rhône makes a sharp turn towards the north. Heading toward Lake Geneva (), the valley narrows near Saint-Maurice, a feature that has long given the Rhône valley strategic importance for the control of the Alpine passes.

Navigation was difficult, as the river suffered from fierce currents, shallows, floods in spring and early summer when the ice was melting, and droughts in late summer. Until the 19th century, passengers travelled in ''coches d'eau'' (water coaches) drawn by men or horses, or under sail. Most travelled with a painted cross covered with religious symbols as protection against the hazards of the journey.
Trade on the upper river used ''barques du Rhône'', sailing barges, , with a capacity. As many as 50 to 80 horses were employed to haul trains of five to seven craft upstream. Goods would be transshipped at Arles into sailing barges called ''allèges d'Arles'' for the final run down to the Mediterranean.

was built at Lyon by Jouffroy d'Abbans in 1783. Regular services were not started until 1829 and they continued until 1952. Steam passenger vessels long made up to and could do the downstream run from Lyon to Arles in a day. Cargo was hauled in ''bateau-anguilles'', boats with paddle wheels amidships, and ''bateaux crabes'', a huge toothed "claw"wheel across to grip the river bed in the shallows to supplement the paddle wheels. In the 20th century, powerful motor barges propelled by diesel engines were introduced, carrying .
In 1933, the Compagnie Nationale du Rhône (CNR) was established to improve navigation and generate electricity, also to develop irrigated agriculture and to protect the riverside towns and land from flooding. Some progress was made in deepening the navigation channel and constructing scouring walls, but World War II brought such work to a halt. In 1942, following the collapse of Vichy France, Italian military forces occupied southeastern France up to the eastern banks of the Rhône, as part of the Italian Fascist regime's expansionist agenda.

on the Upper Rhône (with no lock) in 1948, designed to meet the electricity needs of Paris, twelve hydroelectric plants and locks were built between 1964 and 1980. With a total head of , they produce 13 GWh of electricity annually, or 16% of the country's total hydroelectric production (20% if the Upper Rhône schemes are added). There have been significant benefits for agriculture throughout the Rhône valley.
With the Lower Rhône project completed, CNR turned its attention to the Haut-Rhône (Upper Rhône), and built four hydropower dams in the 1980s: Sault-Brénaz, Brégnier-Cordon, Belley-Brens and Chautagne. It also drew up plans for the high-capacity Rhine-Rhône Waterway, along the route of the existing
