The 3rd federal electoral district of Yucatán () 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 Yucatán.
It elects one deputy to the lower house of Congress for each three-year legislative period 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, elected in the 2024 general election, is of the National Regeneration Movement (Morena).
District territory Yucatán gained a congressional seat in the 2023 redistricting process carried out by the National Electoral Institute (INE). Under the new districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the 3rd district comprises 191 electoral precincts () in the south of the municipality of Mérida.
The head town (), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Mérida. The district had a population of 372,609 in the 2020 census, and with Indigenous and Afrodescendent inhabitants accounting for over 43% of that total, Yucatán's 3rd – like all the state's electoral districts, both local and federal – is classified by the INE as an indigenous district.

Under that plan, Yucatán's district allocation rose from three to four. The 3rd district had its head town at Temax in the northern part of the state.
