# 3rd federal electoral district of Michoacán

The 3rd federal electoral district of Michoacán (Distrito electoral federal 03 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.
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.

## District territory

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, the 3rd district covers 14 municipalities in the north-east of the state:
* Angangueo, Aporo, Contepec, Epitacio Huerta, Juárez, Jungapeo, Maravatío, Ocampo, Senguio, Susupuato, Tlalpujahua, Tuxpan, Tuzantla and Zitácuaro.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Heroica Zitácuaro.

Under the reforms, Michoacán's allocation rose from 9 to 13. The 3rd district's head town was at Zacapu and it covered eight municipalities in the centre of the state:
