The fourth federal electoral district of Guerrero (Distrito electoral federal 04 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.^[a]

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.^[2][3]

Guerrero lost a congressional seat in the 2022 redistricting process. Under the new districting plan, which will be used for the 2024, 2027 and 2030 federal elections,^[4] the fourth district covers the north-western portion of the municipality of Acapulco, comprising 237 precincts (secciones electorales); the remainder of the municipality makes up the second district.^[5]

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the resort city of Acapulco.^[6]

2017–2022

Between 2017 and 2022, Guerrero was allocated nine electoral districts. The fourth district was located in the western sector of the municipality of Acapulco but with a smaller surface area than under the 2022 plan, covering 223 precincts. The head town was Acapulco.^[7]

2005–2017

The 2005 districting plan assigned Guerrero nine districts. The fourth district covered 221 precincts in the north-west and south of the municipality of Acapulco. The city of Acapulco was its head town.^[8]

1996–2005

Under the 1996 districting plan, which allocated Guerrero ten districts, the fourth district was located in the northern and central part of the state. Its head town was at the city of Iguala and it comprised seven municipalities: Atenango del Río, Copalillo, Eduardo Neri, General Heliodoro Castillo, Huitzuco de los Figueroa, Iguala de la Independencia and Tepecoacuilco de Trujano.^[9][10]

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.^[11] The fourth district had its head town at Acapulco and it covered a part of that city.^[12]
