In the administrative divisions of France, the department (French: département, pronounced [depaʁtəmɑ̃] ^ⓘ) is one of the three levels of government under the national level ("territorial collectivities"), between the administrative regions and the communes. Ninety-six departments are in metropolitan France, with an additional five constituting overseas departments, which are also classified as overseas regions. Departments are further subdivided into 333 arrondissements and 2,054 cantons (as of 2023).^[1] These last two levels of government have no political autonomy, instead serving as the administrative basis for the local organisation of police, fire departments as well as, in certain cases, elections.

Each department is administered by an elected body called a departmental council (sg. conseil départemental, pl. conseils départementaux). From 1800 to April 2015, these were called general councils (sg. conseil général, pl. conseils généraux).^[2] Each council has a president. Their main areas of responsibility include the management of a number of social and welfare allowances, of junior high school (collège) buildings and technical staff, and local roads and school and rural buses, and a contribution to municipal infrastructures.^[3] Local services of the state administration are traditionally organised at departmental level, where the prefect represents the government; however, regions have gained importance since the 2000s, with some department-level services merged into region-level services.

The departments were created in 1790 as a rational replacement of Ancien Régime provinces with a view to strengthen national unity;^[4] the title "department" is used to mean a part of a larger whole.^[5] Almost all of them were named after physical geographical features (rivers, mountains, or coasts), rather than after historical or cultural territories, which could have their own loyalties, or after their own administrative seats. The division of France into departments was a project particularly identified with the French revolutionary leader the Abbé Sieyès,^[6][7] although it had already been frequently discussed and written about by many politicians and thinkers. The earliest known suggestion of it is from 1665 in the writings of d'Argenson.^[8] They have inspired similar divisions in many countries, some of them former French colonies. The 1822 territorial division of Spain (reverted due to the 1823 French intervention ending the trienio liberal) and the 1833 territorial division of Spain, which forms the basis of the present day Provinces of Spain with minor modifications, are also based on the French model of departments of roughly equal size.^[9]

Most French departments are assigned a two-digit number, the Official Geographical Code, allocated by the Institut national de la statistique et des études économiques (Insée).^[10] Overseas departments have a three-digit number. The number is used, for example, in the postal code and was until recently used for all vehicle registration plates. Residents commonly use the numbers to refer to their own department or a neighbouring one, for example inhabitants of Loiret may refer to their department as "the 45". More distant departments are generally referred to by their names, as few people know the numbers of all the departments.

In 2014, President François Hollande proposed abolishing departmental councils by 2020, which would have maintained the departments as administrative divisions, and transferring their powers to other levels of governance.^[11] This reform project has since been scrapped.

The first French territorial departments were proposed in 1665 by Marc-René d'Argenson to serve as administrative areas purely for the Ponts et Chaussées (Bridges and Highways) infrastructure administration.^[12]

Before the French Revolution, France gained territory gradually through the annexation of a mosaic of independent entities. By the end of the Ancien Régime it was organised into provinces. During the Revolution they were dissolved, partly in order to weaken old loyalties. The National Constituent Assembly decided to create a more uniform division into departments (département) and districts in late 1789.^[13] The process began on 4 August 1789 with the elimination of provincial privileges, and a 22 December 1789 decree (with letters patent in January 1790) provided for the termination of the provincial governments.^[13]

The modern department system, as all-purpose units of the government, was decreed on 26 February 1790 (with letters patent on 4 March 1790) by the National Constituent Assembly.^[13] Their boundaries served two purposes:

• Boundaries were chosen to break up France's historical regions in an attempt to erase cultural differences and build a more homogeneous nation.
• Boundaries were set so that every settlement in the country was within a day's ride of the capital of a department. This was a security measure, intended to keep the entire national territory under close control.

The old nomenclature was carefully avoided in naming the new departments. Most were named after an area's principal river or other physical features. Even Paris was in the department of Seine. Savoy, during its temporary occupation, became the department of Mont-Blanc.^[14] The provinces continued to exist administratively until 21 September 1791.^[13]

The number of departments, initially 83, had been increased to 130 by 1809 with the territorial gains of the Republic and of the First French Empire.^[15] Following the defeats of Napoleon in 1814–1815 the Congress of Vienna returned France to its pre-war size and the number of departments was reduced to 86 (three of the original departments having been split). In 1860 France acquired the County of Nice and Savoy, which led to the creation of three new departments.^[16] Two were added from the new Savoyard territory, while the department of Alpes-Maritimes was created from Nice and a portion of the Var department.^[16] The 89 departments were given numbers based on the alphabetical order of their names.^[17]

The department of Bas-Rhin and parts of Meurthe, Moselle, Vosges and Haut-Rhin were ceded to the German Empire in 1871 following France's defeat in the Franco-Prussian War. A small part of Haut-Rhin, however, remained French and became known as the Territoire de Belfort; the remaining parts of Meurthe and Moselle were merged into a new Meurthe-et-Moselle department. When France regained the ceded departments after World War I, the Territoire de Belfort was not reintegrated into Haut-Rhin. In 1922 it became France's 90th department. Likewise the Lorraine departments were not changed back to their original boundaries, and a new Moselle department was created in the regained territory, with slightly different boundaries from the pre-war department of the same name.

The reorganisation of Île-de-France in 1968 and the division of Corsica in 1975 added six more departments, raising the total in Metropolitan France to 96. By 2011, when the overseas collectivity of Mayotte became a department, joining the earlier overseas departments of the Republic (all created in 1946) – French Guiana, Guadeloupe, Martinique and Réunion – the total number of departments in the French Republic had become 101. In 2015 the Urban Community of Lyon was split from Rhône to form the Métropole de Lyon, a sui generis entity, with the powers of both an intercommunality and those of a department on its territory, formally classified as a "territorial collectivity with particular status" (French: collectivité territoriale à statut particulier) and as such not belonging to any department. As of 2019 Corse-du-Sud and Haute-Corse are still administrative departments, although they no longer have the status of departmental "territorial collectivities": region and department functions have been managed by a "single territorial collectivity" since 2018.

Despite the intention to avoid the old nomenclature, often the names of pre-1790 provinces remained in use. For example, the name of Berry, though no longer having an official status, remains in widespread use in daily life.

The removal of one or more levels of local government has been discussed for some years; in particular, the option of removing the departmental level. Frédéric Lefebvre, spokesman for the UMP, said in December 2008 that the fusion of the departments with the regions was a matter to be dealt with soon. This was soon refuted by Édouard Balladur and Gérard Longuet, members of the committee for the reform of local authorities, known as the Balladur Committee.^[18]

In January 2008, the Attali Commission recommended that the departmental level of government should be eliminated within ten years.^[19]

Nevertheless, the Balladur Committee has not retained this proposition and does not advocate the disappearance of the departments, but simply "favors the voluntary grouping of departments", which it suggests also for the regions, with the aim of reducing the number of regions to 15.^[20] This committee advocates, on the contrary, the suppression of the cantons.^[20]
