The 3rd federal electoral district of Zacatecas (Spanish: Distrito electoral federal 03 de Zacatecas) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of four such districts in the state of Zacatecas.
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 second region.
The current member for the district, elected in the 2024 general election, is Ulises Mejía Haro of the National Regeneration Movement (Morena).
