The Saône (French pronunciation: ​[soːn]; Arpitan Sona, Latin: Arar) is a river of eastern France. It is a right tributary of the River Rhône, rising at Vioménil in the Vosges department and joining the Rhône in Lyon, just south of the Presqu'île.The name "Saône" derives from that of the Gallic river goddess Souconna, which has also been connected with a local Celtic tribe, the Sequanes. Monastic copyists progressively transformed "Souconna" to "Saoconna", which ultimately gave rise to "Saône".
