8th federal electoral district of Sinaloa
The 8th federal electoral district of Sinaloa is a defunct federal electoral district of Mexico.
During its existence it elected one deputy to the Chamber of Deputies for each three-year legislative session by means of the first-past-the-post system. Votes cast in the district also counted towards the calculation of proportional representation deputies elected from the country's electoral regions.
The 8th district was created as part 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, Sinaloa's seat allocation rose from five to nine.
It was dissolved by the National Electoral Institute in its 2017 redistricting process because the state's population no longer warranted eight districts.
Accordingly, it elected its first deputy in the 1979 legislative election and its last in the 2015 legislative election.
