The 9th federal electoral district of Guerrero () was a federal electoral district of the Mexican state of Guerrero from 1977 to 2024. An earlier 9th district was abolished in 1930.
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 country's electoral regions.
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 by the National Electoral Institute (INE) in its 2023 redistricting process because the state's population no longer warranted nine districts, though the incumbent deputy, Rosario Merlín García of the National Regeneration Movement (Morena), continued to represent the district until 2024.

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.
