10th federal electoral district of Guanajuato

The 10th federal electoral district of Guanajuato () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 15 such districts in the state of Guanajuato.

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 second region.

Suspended in 1943, Guanajuato's 10th was re-established as part of the 1977 political reforms. The restored district returned its first deputy in the 1979 mid-term election.

The current member for the district, elected in the 2024 general election, is Alejandro Calderón Díaz of the National Regeneration Movement (Morena).

District territory

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 is located in the south of Guanajuato and covers 293 electoral precincts () across seven of the state's 46 municipalities:

The head town (), where results from individual polling stations are gathered together and tallied, is the city of Uriangato. The district reported a population of 415,258 in the 2020 Census.

Previous districting schemes

2017–2022

Between 2017 and 2022, the 10th district's head town was at Uriangato and it covered six of the 2023 municipalities:
*Cortazar, Moroleón, Salvatierra, Santiago Maravatío, Uriangato and Yuriria.

2005–2017

Under the 2005 plan, Guanajuato had only 14 districts. This district's head town was at Uriangato and it covered six municipalities in almost the same configuration as in 2017:
*Moroleón, Salvatierra, Santiago Maravatío, Uriangato and Yuriria, but with Tarimoro replacing Cortazar.

1996–2005

In the 1996 scheme, under which Guanajuato was assigned 15 seats, the district comprised four municipalities in the east of the state:
*Apaseo el Alto (head town), Apaseo el Grande, Comonfort and Santa Cruz de Juventino Rosas.

1978–1996

The districting scheme in force from 1978 to 1996 was the result of the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, Guanajuato's seat allocation rose from 9 to 13. The new 10th district covered four municipalities:
*Dolores Hidalgo (head town), Ocampo, San Diego de la Unión and San Felipe.
