The Château de Chenonceau (French: [ʃa.to də ʃə.nɔ̃.so]) is a French château near the small village of Chenonceaux, in the Indre-et-Loire département of the Loire Valley in France.

The château was built on the site of an old mill on the River Cher, sometime before its first mention in writing in the 11th century. It was designed by the French Renaissance architect Philibert de l'Orme.
