List of Mexican municipalities

The country of Mexico is divided into 31 states and one Federal District. These states are in turn divided into municipalities (Spanish: municipios), which may include more than one population center. This page is a list of all of the municipalities of Mexico, subdivided by state.

Municipalities (municipios in Spanish) are the second-level administrative division in Mexico. The Mexican state of Aguascalientes is subdivided into 11 municipalities. The internal political organization and their responsibilities are outlined in the 115th article of the 1917 Constitution and further expanded in the constitution of the State of Aguascalientes. The largest municipality by population is Aguascalientes with 797,010 residents, whereas the smallest municipality by population is San José de Gracia with 8,443 residents. The largest municipality by land area is also Aguascalientes with a land area of 1,178.85 km^2, and the smallest is Cosío with a land area of 128 km^2.

Each municipality is administratively autonomous; citizens elect a "municipal president" (presidente municipal) who heads an ayuntamiento or municipal council, responsible for providing all the public services for their constituents. This concept, which originated after the Mexican Revolution, is known as a municipio libre ("free municipality"). A municipal president heads the ayuntamiento (municipal council). The municipal president is elected by plurality and cannot be reelected for the next immediate term. The municipal council consists of a cabildo (chairman) with a síndico and several regidores (trustees).
