Third federal electoral district of Aguascalientes

The third federal electoral district of Aguascalientes (Distrito electoral federal 03 de Aguascalientes) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of three such districts in the state of Aguascalientes.

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.
