The 3rd federal electoral district of Quintana Roo (Spanish: Distrito electoral federal 03 de Quintana Roo) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of four such districts in the state of Quintana Roo.
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 third region.
The 3rd district was created as part of the 2005 redistricting process and was first contested in the 2006 general election.
The current member for the district, elected in the 2024 general election, is Luis Humberto Aldana Navarro of the National Regeneration Movement (Morena).
