Third federal electoral district of Veracruz

The third federal electoral district of Veracruz (Distrito electoral federal 03 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 third district covers 11 municipalities in the Olmeca and Papaloapan regions in the south of the state:
 * Acayucan, Chinameca, Cosoleacaque, Isla, Juan Rodríguez Clara, Playa Vicente, San Juan Evangelista, Santiago Sochiapan, Sayula de Alemán, Soconusco and Zaragoza.

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

Previous districting schemes
Between 2017 and 2022, Veracruz was assigned 20 electoral districts. The third district was located in the north of the state, comprising six municipalities in the Huasteca Baja and Totonaca regions: Álamo Temapache, Castillo de Teayo, Cazones de Herrera, Cerro Azul, Tepetzintla and Tuxpan. The head town was the city of Tuxpan de Rodríguez Cano.

Veracruz's allocation of congressional seats fell to 21 in the 2005 redistricting process. Between 2005 and 2017 the 3rd district had its head town at Tuxpan and it covered six municipalities: Álamo Temapache, Cazones de Herrera, Cerro Azul, Tamiahua, Tepetzintla and Tuxpan.

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 3rd district had its head town at Poza Rica and it covered the municipalities of Poza Rica and Coatzintla.
