The 5th federal electoral district of Baja California () is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of nine such districts in the state of Baja California.

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.

The 5th district was created by the 1977 electoral reforms and was first contested in the 1979 mid-term election. The current member for the district, elected in the 2024 general election, is 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, Baja California's seat allocation rose from eight to nine. The 5th district covers 236 precincts () in the urban core of the municipality of Tijuana.

The head town (), where results from individual polling stations are gathered together and tallied, is the city of Tijuana. The district reported a population of 436,234 in the 2020 census.

1996–2005 Between 1996 and 2005, this electoral district covered a similar area to its 2005 limits, except that it extended south as far as Playas de Rosarito, thereby also including a rural area that it has since lost. The link contains maps of the 1996 and 2005 schemes.

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, Baja California's seat allocation rose from three to six. The newly created 5th district covered a part of the city of Tijuana.
