The department is named after the Yonne river, a tributary of the Seine, that flows through the department. The Celts name of the river was Ica-onna (Latin: Icauna) and from this name come the name of the river and of the people living in the department: Icaunais.^[4]

History

During Roman times, the main city in the territory of the present department was Sens, the capital of one Roman province.^[4]

Yonne is one of the original 83 departments created during the French Revolution on 4 March 1790 with Auxerre as its capital.^[5] It was formed from combined parts of the old provinces of Burgundy, Champagne and Île-de-France.^[4]

It was divided in seven districts: Auxerre, Sens, Joigny, Saint-Fargeau, Avallon, Tonnerre and Saint-Florentin.^[5]

In 1800, with the creation of the arrondissements in France, the seven districts were changed into five arrondissements: Auxerre, Avallon, Joigny, Sens and Tonnerre. On 10 September 1926, the arrondissements of Joigny and Tonnerre were eliminated.^[5]
