An agglomeration community ({{langx|fr|communauté d'agglomération}}, {{IPA|fr|kɔmynote daɡlɔmeʁasjɔ̃|pron}}) is a consortium of communes (municipalities) in France, created as a government structure by the Chevènement Law of 1999. It is one of four forms of intercommunality, less integrated than a {{lang|fr|métropole}} or a communauté urbaine but more integrated than a communauté de communes. Agglomeration communities consist of a commune of at least 15,000 inhabitants (or a prefecture with less than 15,000 inhabitants) and its independent suburbs.

As of January 2025, there are 230 agglomeration communities in France (214 in metropolitan France and 16 in the overseas departments).[https://www.banatic.interieur.gouv.fr/synthese/france_1?typePerimetre=france&perimetre= Nombre de groupements depuis le 1er janvier 2007], BANATIC. Accessed 28 May 2025. The population (as of 2022) of the agglomeration communities ranges from 364,744 inhabitants (CA Roissy Pays de France) to 28,318 inhabitants (CA Grand Verdun).

Several former communautés d'agglomération have been converted into communautés urbaines or métropoles, for instance those of Strasbourg, Rouen, Saint-Étienne and Caen.
