Yvelines (French pronunciation:  [ivlin] ( Loudspeaker.svg listen )) is a department in the region of Île-de-France, France. Located west of Hauts-de-Seine, it had a population of 1,431,808 as of 2016. Its main communes are Versailles, Saint-Germain-en-Laye, Mantes-la-Jolie and Rambouillet.



Yvelines was created from the western part of the former department of Seine-et-Oise on 1 January 1968 in accordance with a law passed on 10 January 1964 and a décret d'application (a decree specifying how a law should be enforced) from 26 February 1965. It inherited Seine-et-Oise's official number of 78.

It gained the communes of Châteaufort and Toussus-le-Noble from the adjacent department of Essonne in 1969.

The departmental capital, Versailles, which grew up around Louis XIV's château, was also the French capital for more than a century under the Ancien Régime and again between 1871 and 1879 during the early years of the Third Republic. Since then the château has continued to welcome the French Parliament when it is called upon to sit in a congressional sitting (with both houses sitting together) in order to enact constitutional changes or to listen to a formal declaration by the president. [1]


Yvelines is bordered by the departments of Val-d'Oise on the north, Hauts-de-Seine on the east, Essonne on the southeast, Eure-et-Loir on the southwest, and Eure on the west.

The eastern part of the department, as well as its northern part along the Seine, is part of the Paris metropolitan area, but the rest of the department is rural, much of it covered by the Forest of Rambouillet (also known as the Forest of Yveline, from which the name of the department is derived).

Besides Versailles (the prefecture) and the subprefectures of Mantes-la-Jolie, Rambouillet, and Saint-Germain-en-Laye, important cities include Conflans-Sainte-Honorine, Poissy, Les Mureaux, Houilles, Plaisir, Sartrouville, Chatou, Le Chesnay, and the new agglomeration community of Saint-Quentin-en-Yvelines.

Two regional parks can be found in Yvelines: the Park of the Haute Vallée de Chevreuse and part of the Park of Vexin Français.

Yvelines is home to one of France's best known golf courses, La Tuilerie-Bignon, in the village of Saint-Nom-la-Bretèche.

1This group is made up largely of former French settlers, such as pieds-noirs in Northwest Africa, followed by former colonial citizens who had French citizenship at birth (such as was often the case for the native elite in French colonies), and to a lesser extent foreign-born children of French expatriates. Note that a foreign country is understood as a country not part of France in 1999, so a person born for example in 1950 in Algeria, when Algeria was an integral part of France, is nonetheless listed as a person born in a foreign country in French statistics.
2An immigrant is a person born in a foreign country not having French citizenship at birth. Note that an immigrant may have acquired French citizenship since moving to France, but is still considered an immigrant in French statistics. On the other hand, persons born in France with foreign citizenship (the children of immigrants) are not listed as immigrants.
