Fifth federal electoral district of Veracruz

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

District territory
Veracruz lost a congressional district in the 2022 redistricting plan, which is to be used for the 2024, 2027 and 2030 elections. The reconfigured fifth district covers the municipalities of Poza Rica, Tamiahua, Tihuatlán and Tuxpan in the north of the state.

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the city of Poza Rica de Hidalgo.

Previous districting schemes
Between 2017 and 2022, Veracruz was assigned 20 electoral districts. The fifth district still had its head town at Poza Rica but comprised only three municipalities: Poza Rica, Coatzintla and Tihuatlán.

Veracruz's allocation of congressional seats fell to 21 in the 2005 redistricting process. Between 2005 and 2017 the 5th district had its head town at Poza Rica and it covered four municipalities: Castillo de Teayo, Coatzintla, Poza Rica and Tihuatlán.

Under the 1996 districting plan, which allocated Veracruz 23 districts, the head town was at Poza Rica.

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 5th district had its head town at Misantla and it covered the municipalities of Acajete, Atzalán, Coacoatzintla, Colipa, Chiconquiaco, Jilotepec, Juchique, Landero y Coss, Miahuatlán, Las Minas, Misantla, Nautla, Perote, Tatatila, Tenochtitlán, Tlacolulan, Tonavan, Vega de Alatorre, Vigas de Ramírez, Villa Aldama and Yecuatla.
