The 26th federal electoral district of the State of Mexico (Spanish: Distrito electoral federal 26 del Estado de México) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of 40 such districts in the State of Mexico.^[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]

The 26th district was created by the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, the State of Mexico's seat allocation rose from 15 to 34.^[4] The new districts were first contended in the 1979 mid-term election.

Under the National Electoral Institute's 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections,^[5] the 26th district covers the northern portion of one of the state's 125 municipalities:

• Toluca^[6][7][a]

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 Toluca de Lerdo. In the 2020 Census, the district reported a total population of 451,011.^[1][8]

Under the previous districting plans enacted by the INE and its predecessors, the 26th district was situated as follows:

2017–2022

The northern part of the municipality of Toluca. The head town was at Toluca de Lerdo.^[10][11]
