# 9th federal electoral district of Guerrero

The 9th federal electoral district of Guerrero (Distrito electoral federal 09 de Guerrero) is a defunct federal electoral district of the Mexican state of Guerrero.
During its existence, the 9th district returned one deputy to the Chamber of Deputies for each of the 51st to 65th sessions of Congress. Votes cast in the district also counted towards the calculation of proportional representation ("plurinominal") deputies elected from the third region.
Created as part of the 1977 political reforms, it was first contested in the 1979 mid-term election and elected its last deputy in the 2021 mid-terms. It was dissolved during the National Electoral Institute's 2022 redistricting process because the state's population no longer warranted nine districts.

## Territory
### 2017–2022

In its final form, the 9th district covered 159 electoral precincts (secciones electorales) in the municipality of Acapulco. The head town (cabecera distrital), where results from individual polling stations were gathered together and tallied, was the port city of Acapulco.

### 2005–2017

Guerrero lost its 10th district in the 2005 redistricting process. Between 2005 and 2017, the 9th district comprised 162 precincts in the eastern portion of the municipality of Acapulco. The head town was Acapulco.

### 1996–2005

Under the 1996 districting plan, which allocated Guerrero ten districts, the 9th district was located in the municipality of Acapulco. It covered a part of the urban area and the municipality's rural hinterland. The head town was at Acapulco.

### 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 newly created 9th district had its head town at Tecpan de Galeana in the Costa Grande region and it covered the municipalities of Atoyac de Álvarez, Benito Juárez, José Azueta, Petatlán, Tecpan de Galeana and La Unión.
