The Saône (French pronunciation: [soːn]; Arpitan Sona) is a river of eastern France. It is a right tributary of the River Rhône. Rising at Vioménil in the Vosges department, it joins the Rhône in Lyon.
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". The other recorded ancient names for the river were Brigoulus and Arar.
