Michoacán's federal electoral districts since 2022Michoacán under the 2017–2022 districting scheme
The 10th federal electoral district of Michoacán (Distrito electoral federal 10 de Michoacán) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eleven such districts in the state of Michoacán.[1]
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 fifth region.[2][3]
Suspended in 1930,[a]
the 10th district was re-established by the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under the reforms, Michoacán's allocation rose from 9 to 13.[7] The restored tenth district elected its first deputy in the 1979 mid-term election.

Michoacán lost its 12th district in the National Electoral Institute's 2022 redistricting process. Under the new districting plan, which is to be used for the 2024, 2027 and 2030 federal elections,[8]
the 10th district covers 208 electoral precincts (secciones electorales) in the south-east sector of the municipality of Morelia.[9][b]
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Morelia.[1]

^An amendment to Article 52 of the Constitution in 1928 changed the original provision of "one deputy per 60,000 inhabitants" to "one deputy per 100,000";[4][5] as a result, the size of the Chamber of Deputies fell from 281 in the 1928 election to 171 in 1934.[6]
^The remainder of the municipality makes up the 8th district.
