The second federal electoral district of Quintana Roo (Distrito electoral federal 02 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 district was created upon Quintana Roo's statehood in 1974.

District territory

Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the second district covers five of the state's 11 municipalities: The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the state capital, the city of Chetumal. With Indigenous and Afrodescendent inhabitants accounting for over 49% of the population, Quintana Roo's second is classified by the National Electoral Institute (INE) as an indigenous district: the only one in the state.

Previous districting schemes

The 2017 redistricting process assigned Quintana Roo its fourth district. From 2017 to 2022, the second district had its head town at Chetumal and it comprised four municipalities: The 2005 districting scheme created the state's third district. Between 2005 and 2017, the second district covered three municipalities: Othón P. Blanco, Felipe Carrillo Puerto and José María Morelos. The head town was the city of Chetumal. Between 1996 and 2005, the district covered the same three municipalities as under the 2005 plan. 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; Quintana Roo's allocation, however, remained at two. The second district's head town was at Cozumel and it comprised five of the state's (at the time) seven municipalities: Quintana Roo was admitted to the union on 8 October 1974. Prior to that, as a federal territory, it was allowed only one seat in the Chamber of Deputies (for the first district). The second district was created upon statehood in 1974, by halving the territory of the first district; it elected its first deputy in a special election in 1974.
