The 2021 Coahuila elections was held on June 6, 2021, to decide the 38 Municipalities top level positions around the state. Municipal elections in Coahuila allow the people to elect members of the Ayuntamiento (City Council) in each municipality. These are called the 38 municipal presidents (Mayors), 74 sindicos and 400 regidores (city councilors). The term of office of councilors, the mayor and his deputies is, in principle, three years. The municipal elections are sanctioned by Electoral Institute of Coahuila since its creation in 2016.
By the 2021, Institutional Revolutionary Party holds 18 out of 38 municipalities seeking to retain them and with the additional goal of winning more. National Action Party holds 12 municipalities, though, its electoral preferences are plummeted. Meanwhile, federal government party National Regeneration Movement holds 4 municipalities (Piedras Negras, Parras, Francisco I. Madero, and Matamoros) since 2018 and during June counts with high-expectations in Coahuila to obtain more municipalities due to the Lopez Obrador popularity.
