Vernouillet (French pronunciation: [vɛʁnujɛ]) is a commune in the Eure-et-Loir department in northern France.

It lies adjacent to the south side of the town of Dreux.

Built prior to World War II as a civil airport, Vernouillet Airport was seized by the Germans in June 1940 during the Battle of France.

It was liberated by Allied ground forces about 21 August 1944 during the Northern France Campaign.

Declared operational on 26 August, the airfield was designated as "A-41", and was used by combat units until the end of the war.
