9th federal electoral district of Chihuahua

The 9th federal electoral district of Chihuahua (Spanish: Distrito electoral federal 09 de Chihuahua) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of nine such districts in the state of Chihuahua.^[1]

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 first region.^[2][3]

The 9th district was created as part of the 1977 electoral reforms. Under the 1975 districting plan, Chihuahua had only six congressional districts;^[4] with the 1977 reforms, the number increased to ten.^[5] The newly created district elected its first deputy in the 1979 mid-term election.

The current member for the district, elected in the 2024 general election, is Noel Chávez Velázquez of the Institutional Revolutionary Party (PRI).^[6][7]

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,^[8] the 9th district comprises 413 electoral precincts (secciones electorales) across 27 municipalities in the south of the state:^[9][10]
