The 1st federal electoral district of Oaxaca (Spanish: Distrito electoral federal 01 de Oaxaca) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 10 such districts in the state of Oaxaca.
It elects one deputy to the lower house of Congress for each three-year legislative period 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 third region.
The current member for the district, elected in the 2024 general election, is Miriam de los Ángeles Vázquez Ruiz. Originally elected for the Labour Party (PT), on 19 September 2024 she announced she was joining the National Regeneration Movement (Morena).
