Mauregard (French pronunciation: [moʁɡaʁ] ⓘ) is a commune in the Seine-et-Marne department in the Île-de-France region in north-central France.

Parts of the Charles de Gaulle International Airport (France's largest and busiest airport) are located in Mauregard, including Terminal 1 and Terminal 3.

The large airport property (over 8,000 acres (3,200 ha)) straddles land in three départements and six communes, with the Roissy-en-France commune providing its alternate name of Roissy Airport.

There is a single preschool and elementary school, Ecole de Mauregard.
