The 1st federal electoral district of 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 current member for the district, re-elected in the 2024 general election, is of the Ecologist Green Party of Mexico (PVEM).

District territory 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, the 1st district covers 229 precincts () across four of the state's 11 municipalities: Cozumel, Lázaro Cárdenas, Puerto Morelos and Solidaridad.

The head town (), where results from individual polling stations are gathered together and tallied, is the city of Playa del Carmen, the municipal seat of Solidaridad. The district reported a population of 478,518 in the 2020 census.

2017–2022 The 2017 redistricting process assigned Quintana Roo its 4th district. From 2017 to 2022, the 1st district comprised the municipalities of Cozumel, Lázaro Cárdenas, Solidaridad, Isla Mujeres and Tulum.

2005–2017 The 2005 districting scheme created the state's 3rd district. Between 2005 and 2017 the 1st 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.

1996–2005 Between 1996 and 2005, the 1st 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 link provides a complete list of the municipalities covered. The link contains comparative maps of the 1996 and 2005 schemes.

1978–1996 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 1st 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.

Prior to 1978 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 2nd district was created upon statehood in 1974, halving the territory of the 1st district.
