The 16th federal electoral district of the State of Mexico () 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.
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.
Suspended in 1930, the 16th district was re-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. The new districts were first contended in the 1979 mid-term election.
The current member for the district, elected in the 2024 general election, is Emilio Manzanilla Téllez of the Labour Party (PT).
