Croissy-sur-Seine is a commune in the Yvelines department in the Île-de-France region in north-central France. It is a small but very affluent suburban town on the western outskirts of Paris. Many French noble families live or used to live here, as well as artists. Also affluent expatriates can afford Croissy as residence place and choose it due to the presence of the prestigious British School of Paris, which is among the 5 best international schools in the world. The French journalist and drama critic Louis Ganderax (1855–1940) died in the commune.

Croissy was Russia's base camp for Euro 2016, which ran from June 10 to July 10, 2016.


Croissy is located on a loop of the river Seine, which forms its eastern, southern, and western boundaries. Croissy's landward neighbours are Chatou, Le Vesinet, and Le Pecq.

The "centre-ville" provides a reasonable number of shops from bakeries to banks. An active morning market takes place on Fridays and Sundays.

There are several parks, some situated on the islands in the Seine. The commune is home to the 13th century chapel of St Leonard, situated near the banks of the Seine.


In good traffic conditions, the centre of Paris is 20 minutes from Croissy; in daily commuting conditions it will take one hour.

Croissy is not directly served by rail transportation since the commune wants to keep the area residential. The nearest RER station is Chatou-Croissy (on the RER A line St Germain branch). The nearest SNCF service is at Bougival
