The communes of the Morbihan department form the lowest tier of local government in this part of northwestern France. There are 261 communes in Morbihan, each governed by a municipal council and mayor. Communes vary widely in character and size: from historic urban centers to tiny coastal or inland villages, and they are the principal providers of many day‑to‑day public services.
Administrative structure and intercommunal cooperation
Communes exist within the departmental framework of Morbihan, itself one of the administrative département units of the French state. To manage services and development at a broader scale, many communes participate in intercommunal bodies. Notable examples include the Communauté d'agglomération of Pays de Lorient (CAL), created in 2000, and the Communauté d'agglomération of Pays de Vannes (CAV), created in 2001. Another multi‑commune structure is the Communauté d'agglomération of Côte du Pays Blanc (CAB), established in 2003; much of the CAB lies outside Morbihan in the neighbouring Loire-Atlantique.
Geography, economy and local services
Morbihan’s communes span a coastal fringe—marked by islands and the Gulf of Morbihan—to inland bocage and river valleys. Economies reflect this diversity: fishing, maritime commerce and tourism dominate in coastal communes, while agriculture, light industry and services are important inland. Communes are responsible for elementary schools, local roads, urban planning at the municipal level, and many cultural and social programs.
History and evolution
The modern commune structure dates to the reforms enacted during and after the French Revolution, when local jurisdictions were standardized across the country. Since then, the number and boundaries of communes have evolved through mergers, intercommunal cooperation and occasional territorial adjustments. For a complete enumeration and current names see the list of communes for the department.
