The 1st federal electoral district of Mexico City (Spanish: Distrito electoral federal 01 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 22 such districts in Mexico City.
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.
César Cravioto Romero of the National Regeneration Movement (Morena) was elected for the district in the 2024 general election but resigned his seat at the start of the congressional session. He was replaced by his alternate, Jesús Emiliano Álvarez López.
