The 7th federal electoral district of San Luis Potosí () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of seven such districts in the state of San Luis Potosí.
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 second region.
Suspended in 1943, the 7th district was re-established as part 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, San Luis Potosí's seat allocation rose from five to seven. The two new districts were first contested in the 1979 legislative election.
The current member for the district, elected in the 2024 general election, is Briceyda García Antonio 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, the 7th district is in the extreme south-east of the state, covering much of its Huasteca region. It comprises 285 electoral precincts () across 13 of the state's municipalities: Aquismón, Axtla de Terrazas, Coxcatlán, Huehuetlán, Matlapa, San Antonio, San Martín Chalchicuautla, Tamazunchale, Tampacán, Tampamolón, Tancanhuitz, Tanlajás and Xilitla.
The district's head town (), where results from individual polling stations are gathered together and tallied, is the city of Tamazunchale.
The district reported a population of 379,671 in the 2020 census. With Indigenous and Afrodescendent inhabitants accounting for over 80% of that total, it is classified by the INE as an indigenous district – the only indigenous federal electoral district in the state.
