Nineteenth federal electoral district of Veracruz

The nineteenth federal electoral district of Veracruz (Distrito electoral federal 19 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 19th district was created in 1978 and was first contested in the 1979 legislative election.

The districting scheme in force from 1978 to 1996 was the result of the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, Veracruz's seat allocation rose from 15 to 23. The newly created 19th district had its head town at Martínez de la Torre, to the north of the state capital at Xalapa, and it covered the municipalities of Altotonga, Jalacingo, Martínez de la Torre, Tecolutla and Tlapacoyan.
