Nuevo León's districts in 2017–2022

The 3rd federal electoral district of Nuevo León (Spanish: Distrito electoral federal 03 de Nuevo León) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 14 such districts in the state of Nuevo León.

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 Clara Luz Flores of the National Regeneration Movement (Morena).

Under the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections, Nuevo León's congressional seat allocation rose from 12 to 14. The third district is in the northern part of the Monterrey metropolitan area and covers 158 electoral precincts (secciones electorales) in the municipality of General Escobedo.

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of General Escobedo. The district reported a population of 470,320 in the 2020 Census.

Between 2017 and 2022, the district comprised the municipality of General Escobedo (124 precincts).

2005–2017

Under the 2005 districting plan, the district covered the whole of General Escobedo (64 precincts) and 74 precincts in the municipality of San Nicolás de los Garza. The head town was at General Escobedo.

From 1996 to 2005, the district's head town was at San Nicolás de los Garza. It covered the northern portion of San Nicolás (87 precincts) and the whole of General Escobedo (64 precincts).

1978–1996

The districting scheme in force from 1978 to 1996 was the result of the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, Nuevo León's seat allocation rose from 7 to 11. The 3rd district's head town was the state capital, Monterrey, and it covered a portion of that city.
