4th federal electoral district of Coahuila

The 4th federal electoral district of Coahuila () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eight such districts in the state of Coahuila.

It elects one deputy to the lower house of Congress for each three-year legislative session using 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.

The current member for the district, re-elected in the 2024 general election, is Jericó Abramo Masso of the Institutional Revolutionary Party (PRI).

District territory

In its 2023 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the National Electoral Institute (INE) assigned Coahuila an additional district. The reconfigured 4th district covers 187 electoral precincts () in the north-eastern, urban portion of the municipality of Saltillo.

The district's head town (), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Saltillo. The district reported a population of 443,238 in the 2020 Census.
