Club Ciudad de Buenos Aires, familiarly nicknamed as "Muni", is an Argentine sports and social club located in the Núñez neighbourhood of the city of Buenos Aires. The institution was founded on October 6, 1920.

The nickname "Muni" is a diminutive of the word "Municipalidad", which was the way the Government of Buenos Aires seat was called until the 1994 reform of the Argentine Constitution. Since then, the Executive is called "Jefe de Gobierno" ("Chief of Government") instead of "Intendente" ("Mayor") and the former "Municipalidad" denomination became obsolete.
