The commune is situated in the Plaine de Versailles, a fertile agricultural plain. It is bordered by Saint-Cyr-l'École to the east, Bois-d'Arcy to the south, Villepreux to the west, and Rennemoulin to the north.

The name "Fontenay" derives from the Latin Fontanetum, meaning "the place of springs," referring to the numerous water sources in the area that feed the Rue de Gally. In the 11th century, the village was a dependency of the Abbey of Saint-Germain-des-Prés. Under the reign of Louis XIV, the village became part of the Royal Domain of the Palace of Versailles. The king's influence is still visible in the architecture of the "Plaine de Gally." During the early 20th century, Fontenay's proximity to the Saint-Cyr-l'École air base linked it to the birth of French aviation, as pioneers like Alberto Santos-Dumont and Henri Farman performed maneuvers over the surrounding fields.

The commune is served by the Fontenay-le-Fleury station on the Transilien Paris-Montparnasse line (Line N), providing direct access to Gare Montparnasse in approximately 30 minutes. It is also connected to the local bus network of the Communauté d'agglomération Versailles Grand Parc.
