An '''agglomeration community''' ({{langx|fr|communauté d'agglomération}}, {{IPA|fr|kɔmynote daɡlɔmeʁasjɔ̃|pron}}) is a [[consortium]] of [[communes in France|communes]] ([[municipality|municipalities]]) in [[France]], created as a government structure by the [[Jean-Pierre Chevènement|Chevènement]] Law of 1999. It is one of four forms of [[commune in France#Intercommunality|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 [[communes in France|commune]] of at least 15,000 inhabitants (or a [[prefectures in France|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 department]]s).<ref>[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.</ref> The population (as of 2022) of the agglomeration communities ranges from 364,744 inhabitants ([[Communauté d'agglomération Roissy Pays de France|CA Roissy Pays de France]]) to 28,318 inhabitants ([[Communauté d'agglomération du Grand Verdun|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]].
