23rd federal electoral district of Mexico City

The 23rd federal electoral district of Mexico City (Distrito electoral federal 23 de la Ciudad de México; previously "of the Federal District") is a defunct Mexican electoral district. It was in existence from 1961 to 2023.

During that time, it returned one deputy to the Chamber of Deputies for each three-year legislative session by means of the first-past-the-post system, electing its first in the 1961 mid-term election and its last in the 2021 mid-terms. From 1979 onwards, votes cast in the district also counted towards the calculation of proportional representation ("plurinominal") deputies elected from the country's electoral regions.

The 23rd and 24th districts were abolished in the National Electoral Institute's 2022 redistricting process because the capital's population no longer warranted that number of seats in Congress.
