Le Chesnay (French pronunciation: [lə ʃɛnɛ] ⓘ) is a former commune in the Yvelines department in the Île-de-France region in north-central France.

On 1 July 1815, Napoleon's Grande Armée fought its last battle in Rocquencourt and Le Chesnay.

While negotiating the final armistice, Exelmans was ordered to attack the Prussians at Versailles on 1 July 1815.

(From Presentation of Rocquencourt) Le Chesnay is not served by any station of the Paris Métro, RER, or suburban rail network.

This station is located in the neighboring city of Versailles, 2 km (1.2 mi) from the town center of Le Chesnay.
