The twentieth federal electoral district of Veracruz (Distrito electoral federal 20 de Veracruz) is a defunct federal electoral district of the Mexican state of Veracruz.

During its existence, the 20th district returned one deputy to the Chamber of Deputies for each of the 51st to 65th sessions of Congress. Votes cast in the district also counted towards the calculation of proportional representation ("plurinominal") deputies elected from the country's electoral regions.

Created as part of the 1977 political reforms, it was first contested in the 1979 mid-term election and it elected its last deputy in the 2021 mid-terms. It was dissolved in the 2022 redistricting process because the state's population no longer warranted 20 districts.

2017–2022

In its final form, the 20th district comprised 14 municipalities: Cosoleacaque, Chinameca, Hueyapan de Ocampo, Jáltipan, Mecayapan, Oluta, Oteapan, Pajapan, Soconusco, Soteapan, Texistepec, Zaragoza, Nanchital and Tatahuicapan. The district's head town (cabecera distrital), where results from individual polling stations were gathered together and collated, was the city of Cosoleacaque.

2005–2017

Between 2005 and 2017 the 20th district's head town was the city of Acayucan. It covered 11 municipalities in the south-east of the state: Acayucan, Chacaltianguis, Isla, Juan Rodríguez Clara, Playa Vicente, San Juan Evangelista, Sayula de Alemán, José Azueta, Tuxtilla, Carlos A. Carrillo and Santiago Sochiapan.

1996–2005

Under the 1996 districting plan, the district's head town was at Acayucan.

1978–1996

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 20th district had its head town at Zongolica, and it covered the municipalities of Acultzingo, Astacinga, Atlahuilco, Camerino Z. Mendoza, Coetzala, Cuichapa, Cuitláhuac, Magdalena, Mixtla de Altamirano, Naranjal, Omealca, Los Reyes, San Andrés Tenejapan, Soledad Atzompa, Tehuipango, Tequila, Texhuacán, Tezonapa, Tlaquilpa, Tlilapan, Xoxocotla, Yanga and Zongolica.
