The 9th federal electoral district of 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 9th district was created by the 1977 electoral reforms and was first contested in the 1979 mid-term election.
The current member for the district, re-elected in the 2024 general election, is of the Institutional Revolutionary Party (PRI).
