The 9th federal electoral district of Chiapas () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 13 such districts in the state of Chiapas.
It elects one deputy to the lower house of Congress for each three-year legislative session 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 third region.
The 9th district was established as part of the 1977 electoral reforms. Under the 1975 districting plan, Chiapas had only six congressional districts; with the 1977 reforms, the number increased to nine. The newly created district elected its first deputy in the 1979 mid-term election.
The current member for the district, elected in the 2024 general election, is Guillermo Rafael Santiago Rodríguez of the National Regeneration Movement (Morena).
District territory Under the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections, Chiapas's 9th district comprises 168 electoral precincts (secciones electorales) in the municipality of Tuxtla Gutiérrez.
The head town (), where results from individual polling stations are gathered together and tallied, is the state capital, Tuxtla Gutiérrez. The district reported a population of 435,135 in the 2020 census.
