阿尔沃河（法语：Arve）是罗纳河的支流，发源于法国上萨瓦省的勃朗峰山地，在瑞士日内瓦注入罗纳河。

沿途经过的城镇有：法国夏慕尼、萨朗什（Sallanches）、克吕兹（Cluses）、阿纳马斯和瑞士日内瓦。

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.
