The third federal electoral district of Chihuahua (Distrito electoral federal 03 de Chihuahua) 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 currently operating in the state of Chihuahua.

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.

Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the third district covers the western portion of Ciudad Juárez and the municipality of Juárez, together with the adjacent municipalities of Ascensión and Janos.

Its head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Ciudad Juárez.

2017–2022

Between 2017 and 2022 the district comprised the western portions of Ciudad Juárez and the municipality of Juárez. Its head town was Ciudad Juárez.

2005–2017

Under the 2005 districting scheme, Chihuahua's third district covered the eastern portion of Ciudad Juárez, which served as its head town.

1996–2005

Chihuahua lost its tenth district in the 1996 redistricting process. The reconfigured third district covered the eastern portion of Ciudad Juárez and the southern reaches of the municipality of Juárez.

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, Chihuahua's seat allocation rose from six to ten. Between 1979 and 1996, the third district occupied a part of Ciudad Juárez.
