(; French for "urban community") is the second most integrated form of intercommunality in France, after the Metropolis (). A is composed of a city (commune) and its independent suburbs (independent communes).
The first communautés urbaines were created by the French Parliament on 31 December 1966. Originally there were only four, found in the metropolitan areas of Bordeaux, Lille, Lyon and Strasbourg. Later, others were created in other metropolitan areas. The purpose of the communautés urbaines was to achieve cooperation and joint administration between large cities and their independent suburbs. This step often followed failed attempts to merge the communes within a metropolitan area. The status of the communauté urbaine was modified by the Chevènement Law of 1999. Since the creation of the métropoles in 2011, several former communautés urbaines have become métropoles, for instance Nice, Strasbourg, Marseille, Nancy and Dijon.
Unlike the case in either a communauté d'agglomération or communauté de communes, communes cannot leave a communauté urbaine freely.
As of January 2025, there are 14 communautés urbaines in France (all in metropolitan France), with a combined population of 3.17 million inhabitants (as of 2022, in 2025 limits).
