The Yonne River is an important river located in the northern part of France. It flows mostly through the western area of the Bourgogne-Franche-Comté region. The river is so significant that it gave its name to the Yonne department and to many towns, called communes, along its path. The Yonne is the main river that joins the Seine river from its left side.
During the time of the Roman Empire, the river was known as Icauna. This Latin name probably came from an older Celtic name for the river.

The Yonne river generally flows from the southeast towards the northwest. It passes through 115 different communes (towns). Most of these towns are in the Bourgogne-Franche-Comté region. Some of the main towns it flows through include:
- In Nièvre (department number 58): Corbigny and Clamecy.
- In Yonne (department number 89): Auxerre, Joigny, Sens, Pont-sur-Yonne, and Villeneuve-sur-Yonne.
- In Seine-et-Marne (department number 77): Montereau-Fault-Yonne.
Finally, the Yonne river joins the Seine river in the town of Montereau-Fault-Yonne. It joins the Seine as a left tributary, meaning it flows into the Seine from the left side if you are looking downstream. This meeting point is about 47 m (154 ft) above sea level.
