The seventh federal electoral district of Coahuila (Distrito electoral federal 07 de 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.[1]
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.[2][3]
Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections and which gave Coahuila an additional district,[5]
the 7th district covers the more rural portion of the municipality of Saltillo. Its head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the state capital, the city of Saltillo.[6][1]

^An amendment to Article 52 of the Constitution in 1928 changed the original provision of "one deputy per 60,000 inhabitants" to "one deputy per 100,000";[11][12] as a result, the size of the Chamber of Deputies fell from 281 in the 1928 election to 171 in 1934.[13]
