12th federal electoral district of Chiapas


The 12th 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 deputies elected from the third region.
The 12th district was created in 1996. Between 1979 and 1996, the state had only nine congressional districts; the 1996 redistricting process increased the number to 12. The three new districts elected their first deputies in the 1997 mid-terms.
The current member for the district, elected in the 2024 general election, is of the National Regeneration Movement.
