# 3rd federal electoral district of Guerrero

The 3rd federal electoral district of Guerrero (Distrito electoral federal 03 de 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 ("plurinominal") deputies elected from the fourth region.

## District territory

Guerrero lost a congressional seat in the National Electoral Institute's 2022 redistricting process, but the 3rd district was unaffected by the resulting boundary changes. Under the new districting plan, which will 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 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.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the port city of Zihuatanejo.

## Previous districting schemes
### 2017–2022

Between 2017 and 2022, the 3rd district had the same configuration as under the 2022 plan, despite the state having an additional district.

### 2005–2017

Guerrero had nine districts under the 2005 districting plan. The 3rd district was located in the Costa Grande region, with almost the same composition as in the later plans: the southernmost municipality of Coyuca de Benítez, adjacent to Acapulco, was assigned to the seventh district. The head town was at Zihuatanejo.

### 1996–2005

Under the 1996 districting plan, which allocated Guerrero ten districts, the district comprised the same seven municipalities as in the 2005 plan, with its head town at Zihuatanejo.

### 1978–1996

The districting scheme in force from 1978 to 1996 was the result of the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, Guerrero's district allocation rose from six to ten. The 3rd district was located inland: it had its head town at Coyuca de Catalán and it covered the municipalities of Ajuchitlán del Progreso, Apaxtla, Coahuayutla, Coyuca de Catalán, General Heliodoro Castillo, Leonardo Bravo, Pungarabato, San Miguel Totolapan, Zirándaro and Zumpango del Río.
