The 5th federal electoral district of Sonora () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of seven such districts in the state of Sonora.
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 first region.
Suspended in 1930, the 5th district was re-established in 1978 and was contested again in the 1979 legislative election.
The current member for the district, elected in the 2024 general election, is Jacobo Mendoza Ruiz of the National Regeneration Movement (Morena).
District territory Under the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections, Sonora's 5th district covers 217 electoral precincts () in the south-eastern half of the municipality of Hermosillo.
The head town (), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Hermosillo. The district reported a population of 468,661 in the 2020 census.

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, Sonora's seat allocation rose from four to seven. The restored 5th district had its head town at San Luis Río Colorado and it covered 14 municipalities in the state's north-west: Altar, Atil, Benjamín Hill, Caborca, Carbó, Opodepe, Oquitoa, Pitiquito, Puerto Peñasco, San Luis Río Colorado, Santa Ana, Sáric, Trincheras and Tubutama.
