The 7th 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.
Suspended in 1930, the 7th district was re-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 restored 7th district elected its first deputy in the 1979 mid-term election.
The current member for the district, elected in the 2024 general election, is Azucena Arreola Trinidad 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 7th district covers 214 electoral precincts () across nine municipalities along the Pacific Ocean coast and the border with the state of Oaxaca: Acacoyagua, Acapetahua, Arriaga, Cintalapa, Escuintla, Jiquipilas, Mapastepec, Pijijiapan and Tonalá.

Under that plan, Chiapas's seat allocation rose from six to nine. The restored 7th district had its head town at Huixtla and it covered 14 municipalities.
