The 3rd federal electoral district of Aguascalientes (Spanish: Distrito electoral federal 03 de Aguascalientes) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of three such districts in the state of Aguascalientes.
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 third district was re-established as part of the 1996 redistricting processand has returned deputies to Congress since the 1997 legislative election. The current member for the district, re-elected in the 2024 general election, is Paulo Gonzalo Martínez López of the National Action Party (PAN).
