The first federal electoral district of Quintana Roo (Distrito electoral federal 01 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.

District territory

Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the first district covers four 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 city of Playa del Carmen, the municipal seat of Solidaridad.

Previous districting schemes

The 2017 redistricting process assigned Quintana Roo its fourth district. From 2017 to 2022, the first district comprised the municipalities of Cozumel, Lázaro Cárdenas, Solidaridad, Isla Mujeres and Tulum. The 2005 districting scheme created the state's third district. Between 2005 and 2017 the first district covered the municipalities of Cozumel, Isla Mujeres, Lázaro Cárdenas, Solidaridad, Tulum, and the non-urban area of the municipality of Benito Juárez (i.e., excluding the city and resort of Cancún). Its head town was the city of Playa del Carmen. Between 1996 and 2005, the first district's territory was the same under the 2005 plan, except that it included the entirety of Benito Juárez, including the city and resort of Cancún. Cancún also served as the district's head town for vote-collecting purposes. 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 first district comprised two of the state's (at the time) seven municipalities: José María Morelos and Othón P. Blanco, with the latter serving as its head town. Quintana Roo was admitted to the union on 8 October 1974. Prior to that, as a federal territory, it was assigned only one seat in the Chamber of Deputies: for the first district. The second district was created upon statehood in 1974, halving the territory of the first district.
