Seine-et-Marne (French pronunciation: [sɛn e maʁn] ) is a department in the Île-de-France region in Northern France. Named after the rivers Seine and Marne, it is the region's largest department with an area of 5,915 square kilometres (2,284 square miles); it roughly covers its eastern half. In 2019, it had a population of 1,421,197.[4] Its prefecture is Melun, although both Meaux and Chelles have larger populations.


Seine-et-Marne is one of the original 83 departments created on 4 March 1790 during the French Revolution in application of the law of 22 December 1789. It had previously belonged to the former province of Île-de-France. It is the only original departement in the Île-de-France that has remained unchanged, as both Seine and Seine-et-Oise were abolished and reorganised in 1968.



Prefecture building of the Seine-et-Marne department in Melun

Seine-et-Marne forms a part of the Île-de-France region; the department covers 49% of the region's land area. It is bordered by Val-d'Oise, Seine-Saint-Denis, Val-de-Marne, Essonne to the west; Loiret and Yonne to the south; Aube and Marne to the east; and Aisne and Oise to the north. It is served by RER A, RER B, RER D and RER E amongst other services.

Melun is Seine-et-Marne's prefecture. Fontainebleau, Meaux, Provins and Torcy are its subprefectures. The department comprises part of Paris's outer eastern suburbs; much of Charles de Gaulle Airport sits within its far northwestern boundaries, including a majority of the terminals. The department has many natural reserves, notably Brie and Gâtinais. The department's highest point is butte Saint-George (215 m).

People from Seine-et-Marne are known as the Seine-et-Marnais.

Originally Seine-et-Marne was very rural and lightly populated. Over the past 50 years, however, its population has tripled, due to the development of the Paris conurbation and the building of new towns in the northwest of the region. The population was estimated to be 1,267,496 inhabitants in 2006. The region has changed from consisting only of small villages to forming a large part of the Paris conurbation.

Seine-et-Marne as a whole shares a sister city relationship with Orlando, Florida, United States, as both host Disney theme parks.

1 This 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), as well as to a lesser extent foreign-born children of French expatriates. 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.

2 An immigrant is a person born in a foreign country not having French citizenship at birth. 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.


With 60 percent of the region used as farmland, Seine-et-Marne is where most agricultural activity occurs within Île-de-France. Cereals and sugar beet are the principal exports from Seine-et-Marne.

The other key industrial structures are the refinery at Grandpuits and the Safran Aircraft Engines research plant at Villaroche. The new town of Marne-la-Vallée is the centre of tourism in Seine-et-Marne in terms of number of visitors, mainly due to the Disneyland Park and Walt Disney Studios Park theme parks at Disneyland Paris.
