Fifth federal electoral district of Coahuila

The fifth federal electoral district of Coahuila (Distrito electoral federal 05 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.

It elects one deputy to the lower house of Congress for each three-year legislative period, by means of the first-past-the-post system. Votes cast in this district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the second region.

The current 5th district was created as part of the 1977 political reforms and was first contested in the 1979 mid-term election.
