Seventeenth federal electoral district of Veracruz

The seventeenth federal electoral district of Veracruz (Distrito electoral federal 17 de Veracruz) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 19 such districts in the state of Veracruz.

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 third region.

The 17th district was created in 1978 and was first contested in the 1979 legislative election.
