The 6th 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 1952, the 6th 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 of the Ecologist Green Party of Mexico (PVEM).
