The 20th federal electoral district of Mexico City (Spanish: Distrito electoral federal 20 de la Ciudad de México; previously "of the Federal District") is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of the 22 currently operational districts in Mexico City.[1]

It elects one deputy to the lower house of Congress for each three-year legislative session by means of the first past the post system. Votes cast in the district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the fourth region.[2][3]

The current member for the district, elected in the 2024 general election, is Ana Karina Rojo Pimentel of the Labour Party (PT).[4][5]

Under the 2022 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections,[6] the 20th district covers 278 electoral precincts (secciones electorales) across the north-eastern portion of the borough (alcaldía) of Iztapalapa.[7]

The district reported a population of 477,773 in the 2020 Census.[1]
