The eighth federal electoral district of Chihuahua (Distrito electoral federal 08 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.

The eighth district was created as part of the 1977 electoral reforms. Under the 1975 districting plan, Chihuahua had only six congressional districts; under the 1977 reforms, the number increased to ten. The newly created eighth district elected its first deputy in the 1979 mid-term election.

Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections, the eighth district covers the southern part of the municipality of Chihuahua and the eastern part of the city of Chihuahua.

The district's head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Chihuahua.

2017–2022

Between 2017–2022 the eighth district covered the east and south of the city of Chihuahua and the south of the municipality of Chihuahua.

2005–2017

Under the 2005 districting scheme, the eighth district comprised the eastern and northern portions of the municipality of Chihuahua, including approximately one-half of the urban area of the city of Chihuahua. The head town was the city of Chihuahua. The other half of the city, and the rest of the municipality, was covered by the sixth district.

1996–2005

Chihuahua lost its tenth district in the 1996 redistricting process. Between 1996 and 2005, the eighth district covered the southern portion of the municipality of Chihuahua, the part south of the Río Chuvíscar.

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. The new eighth district covered the urban area of Ciudad Juárez in the north of the state.
