Montigny-le-Bretonneux (French pronunciation: [mɔ̃tiɲi lə bʁətɔnø] (listen)) is a commune in the Yvelines department in the Île-de-France region in north-central France. It is located in the south-western suburbs of Paris, 24.5 kilometres (15.2 miles) from the centre of Paris, in the "new town" of Saint-Quentin-en-Yvelines, of which it is the central and most populated commune.


Montigny-le-Bretonneux, the 8th town of the Yvelines department by population, has 33,000 inhabitants and is the central and principal town of the Saint-Quentin-en-Yvelines district. It is situated at the heart of Yvelines, between the Vallée de Chevreuse and the Forest of Rambouillet in the south, and the towns of Versailles and Saint-Germain-en-Laye in the north.

The history of the town reflects that of a small traditional French village, devoted to agriculture. The growth of the new town in the 1970s actually initiates the change from the village of Montigny-le-Bretonneux (1292 inhabitants in 1970) to the town (10,063 in 1980).

The town is found 25 km (16 miles) south west of Paris, and 5 km (3 miles) from Versailles, and at the heart of an agglomeration of 150,000 people, of which Montigny is the largest commune.

After two decades of steady urbanization, Montigny-le-Bretonneux is now essentially completed, although the opportunity to create new housing is still there. In 2002, the State has decreed the end of the Operation of National Interest Statute establishing the new district of Saint-Quentin-en-Yvelines, whose seven member municipalities have opted for a new intercommunal principal, the “Community of Agglomeration”.

Montigny-le-Bretonneux has now passed the building phase — the frenzy of building that characterised the town is suitably balanced between neighbourhoods and business areas. Montigny has become a haven for St. Quentinois wishing to settle there. The parks were born in the 1970s and 1980s with the rise of the new town are and were in principle built to rehabilitate the economic heritage and to adapt to technological standards now imposed on businesses. Its economy is rooted primarily in the service sector (1,590 businesses). Furthermore, several major headquarters of international companies have settled in the city (for example; SAIPEM, BMW France et COGEMA).

Recent developments in Montigny-le-Bretonneux include the national velodrome built between 2011 and 2014, supported by the State, the French Cycling Federation, local authorities and a pool of business partners, and the Faculty of Medicine (UFR des sciences de la santé Simone Veil), part of the Versailles Saint-Quentin-en-Yvelines University.
