Chessy (French pronunciation: [ʃɛsi] ⓘ) is a commune in the eastern suburbs of Paris, in the Seine-et-Marne department in the Île-de-France region in north-central France.

Chessy is located in Val d'Europe, the fastest growing sector in the "new town" of Marne-la-Vallée.

A village of only 760 inhabitants in 1982, Chessy was since then absorbed by the suburbs of Paris, and due to strong demographic growth the population reached 3,438 in 2007.

[5] There is a junior high school in Chessy, Collège Le vieux Chêne.

Vocational high schools in the surrounding area include Emilie du Châtelet, Lycée technique Pierre de Coubertin, LEP Auguste Perdonnet in Thorigny-sur-Marne, LEP Charles Baudelaire in Meaux, and LEP Louis Lumière in Chelles.
