Le Vésinet is located in a bend of the Seine, but has no access to the river.
It is 16.4 km (10.2 mi) west of Paris and 4 km east of Saint-Germain-en-Laye.
The surrounding communes are Chatou on the east, Croissy-sur-Seine on the south, Le Pecq on the west, and Montesson on the north.

The terrain is an alluvial plain ranging from 28 meters near Le Pecq to 45 meters in altitude at the end of the Route de Montesson, with a gentle slope from northeast to southwest.

The commune is entirely urbanized, principally with single-family dwellings.
Green space comprises 20 percent of the territory.
There are a number of lakes: the lac Supérieur, the lac Inférieur, the lac de la Station, the lac de Croissy, and the Grand lac (with a large central island, l'Île des Ibis) also called Lac des Ibis.
These lakes are linked by nearly 4 km of artificial streams called les Petites Rivières.
