27th federal electoral district of the Federal District

The twenty-seventh federal electoral district of the Federal District () is a defunct federal electoral district of Mexico. Occupying a portion of what is today Mexico City, it was in existence from 1973 to 2017.

During that time, it returned one deputy to the Chamber of Deputies for each three-year legislative session by means of the first-past-the-post system, electing its first in the 1973 mid-term election and its last in the 2015 mid-terms. From 1979 onwards, votes cast in the district also counted towards the calculation of proportional representation ("plurinominal") deputies elected from the country's electoral regions.

The 25th, 26th and 27th districts were abolished by the National Electoral Institute (INE) in its 2017 redistricting process because the capital's population no longer warranted that number of seats in Congress.

2005–2017 In its final form, when the capital accounted for 27 districts, the 27th was located in the south-east of the city. It covered the whole of the borough of Tláhuac. The link contains maps of the 2005 and 1996 schemes.

1996–2005 Under the 1996 scheme, the capital comprised 30 districts. The 27th covered Tláhuac and the neighbouring borough of Milpa Alta to the south. The link contains a detailed description of the 1996 district's territory.

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, the Federal District's seat allocation rose from 27 to 40. The 27th district covered portions of the boroughs of Coyoacán, Iztapalapa and Tlalpan.
