The first federal electoral district of Baja California (Distrito electoral federal 01 de 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.^[1]

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.^[2][3]

Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections,^[4] the first district covers 203 electoral precincts (secciones electorales) in the eastern urban portion of the municipality of Mexicali. The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the state capital, the city of Mexicali.^[5][1][a]

2005–2017

Under the 2005 redistricting process, it was made up of the municipality of Mexicali, with the exception of its extreme northwest (where the state's third district was located) and its extreme northeast (which corresponded to the second district).^[6] The district's head town was the city of Mexicali.

1996–2005

Between 1996 and 2005, this electoral district covered the whole of the municipality of Mexicali, except for a small pocket in the east of the city of Mexicali, which was part of the second district.^[7]
