# 4th federal electoral district of Coahuila

The 4th federal electoral district of Coahuila (Distrito electoral federal 04 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 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.
