The river Arve (French: L'Arve) flows for approximately 100 km (62 miles) through France, in the département of Haute-Savoie, and (for a few kilometers) in Switzerland. It is a left tributary of the Rhône.

Rising in the northern side of the Mont Blanc massif in the Alps, close to the Swiss border, it receives water from the many glaciers of the Chamonix valley (mainly the Mer de Glace) before flowing north-west into the Rhône on the west side of Geneva, where its much higher level of silt brings forth a striking contrast between the two rivers.

The Arve flows through Chamonix, Sallanches, Oëx, Cluses, Bonneville, Annemasse and Geneva.
