The 28th 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 1979 to 2005.
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 1979 mid-term election and its last in the 2003 mid-terms. Votes cast in the district also counted towards the calculation of proportional representation ("plurinominal") deputies elected from the country's electoral regions.
The 28th, 29th and 30th districts were abolished by the Federal Electoral Institute (IFE) in its 2005 redistricting process because the capital's population no longer warranted that number of seats in Congress. They were not contested in the 2006 general election.
