The 10th federal electoral district of Oaxaca () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 10 such districts in the state of Oaxaca.
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.
Oaxaca's 10th district was created as part of the 1977 electoral reforms. Under the 1975 districting plan, Oaxaca had only nine congressional districts; under the 1977 reforms, the number increased to ten. The newly created district elected its first deputy, to the 51st Congress, in the 1979 legislative election.
The current member for the district, elected in the 2024 general election, is Carmelo Cruz Mendoza of the National Regeneration Movement (Morena).
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 10th district covers 275 precincts () across 77 municipalities.
The head town (), where results from individual polling stations are gathered together and tallied, is the city of Miahuatlán de Porfirio DÃÂaz in the Sierra Sur region. The district reported a population of 442,838 in the 2020 Census and, with Indigenous and Afrodescendent inhabitants accounting for over 63% of that total, it is classified by the INE as an indigenous district.
