3rd federal electoral district of Guerrero
The 3rd federal electoral district of Guerrero is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eight such districts in the state of Guerrero.
It elects one deputy to the lower house of Congress for each three-year legislative period by means of the first-past-the-post system. Votes cast in the district also count towards the calculation of proportional representation deputies elected from the fourth region.
The current member for the district, elected in the 2024 general election, is Carmen Cabrera Lagunas of the Ecologist Green Party of Mexico.
District territory
Guerrero lost a congressional seat in the 2023 redistricting process carried out by the National Electoral Institute, but the 3rd district was unaffected by the resulting boundary changes. Under the new districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, it covers the state's Costa Grande region, running from the western outskirts of Acapulco to the border with the state of Michoacán. It comprises 387 electoral precincts across eight municipalities:- Atoyac, Benito Juárez, Coahuayutla, Coyuca de Benítez, La Unión, Petatlán, Tecpan and Zihuatanejo, all of which, except for Atoyac and Coahuayutla, have coastlines along the Pacific.
Previous districting schemes
Because of shifting population patterns, Guerrero currently has two fewer districts than the ten the state was assigned under the 1977 electoral reforms that set the national total at 300.2017–2022
