Villepreux (French: [vilpʁø] ⓘ) is a commune in the Yvelines department in the Île-de-France in north-central France located about 12 km west of Versailles, in the plaine de Versailles, almost in line with the perspective of the Grand Canal (an axis corresponding to the former Allée royale de Villepreux).

Further south, towards the SNCF train station, is the La Haie Bergerie quarter, a subdivision created by Jacques Riboud and his architect Roland Predieri -who later became the Mayor of Villepreux.

Towards the west, is a new division called Trianon, near the Pointe-à-l'Ange area, with built-up quality buildings, pavilions, and lush fields on the edge of the municipality of Chavenay.

This is also the Val Joyeux area, another subdivision of 400 houses, dating from the post-war period and small newer residential houses and apartments on the edge of the forest of Bois d'Arcy.

The town is crossed in its southeastern part (Val Joyeux) by the l'aqueduc de l'Avre.
