The 2nd federal electoral district of Querétaro () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of six such districts in the state of Querétaro.

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; since 2024, those elected from the fifth region.

The current member for the district, elected in the 2024 general election, is Ricardo Astudillo Suárez of the Ecologist Green Party of Mexico (PVEM).

District territory Under the 2023 districting plan adopted by the National Electoral Institute (INE), which assigned Querétaro an additional seat in Congress and is to be used for the 2024, 2027 and 2030 federal elections, the 2nd district covers 145 precincts () across two of the state's 18 municipalities: San Juan del Río and Amealco de Bonfil.

The head town (), where results from individual polling stations are gathered together and tallied, is the city of San Juan del Río. The district reported a population of 364,463 in the 2020 census.
