The Montreal Urban Community (MUC) (French: Communauté Urbaine de Montréal, pronounced [kɔmynote yʁbɛn də mɔ̃ʁeal], CUM) was a regional government in Quebec, Canada, that covered all municipalities located on the Island of Montreal and the islands of L'Île-Dorval and Île Bizard from January 1970 (when it was created from the former Jacques-Cartier County) until the end of December 2001.

After the partial demergers of 2006, a successor organization was formed, the Urban agglomeration of Montreal.

The MUC was first succeeded by Montreal Metropolitan Community (MMC).

Since the merger and subsequent demerger, the MUC has been replaced by the Montreal Agglomeration Council.

This left the MMC in place, so the Agglomeration Council is a supra-municipal entity between the municipal level and the regional municipal level.
