The 9th 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 ("plurinominal") deputies elected from the country's electoral regions.
The 9th 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 Federal Electoral Institute (IFE) in its 1996 redistricting process because the state's population no longer warranted nine districts. Accordingly, it elected its first deputy in the 1979 mid-term election and its last in the 1994 general election.
