Jouars-Pontchartrain is a commune in the Yvelines department in the Île-de-France region in north-central France. It is approximately 35 kilometres from Paris. This city is famous for the Château de Pontchartrain.

Geography
The town of Jouars-Pontchartrain is located 35 km west of Paris, 18 km west of Versailles and 22 km from Rambouillet, on a buttress which delimits the western end of the plain of Versailles and at the foot from which begins the plain of Montfort-l'Amaury. Its territory is irrigated by the Mauldre whose south-north oriented course follows the eastern limit of the town and receives in the park of the Château de Pontchartrain the Élancourt brook, a diversion of which feeds its pond. This brook, oriented east-west, is enlarged a little upstream by the Maurepas brook which joins it at Chennevières.
