The second federal electoral district of Chihuahua (Distrito electoral federal 02 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 second district covers the south of Ciudad Juárez and the adjacent municipalities of Ahumada, Guadalupe and Práxedis G. Guerrero. The district's 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 municipalities of Ahumada, Ascensión, Buenaventura, Casas Grandes, Galeana, Guadalupe, Ignacio Zaragoza, Janos, Nuevo Casas Grandes and Práxedis G. Guerrero, together with the south of the municipality of Juárez and the southern portion of Ciudad Juárez.

2005–2017

Under the 2005 districting scheme, Chihuahua's second district covered the western portion of Ciudad Juárez and of the surrounding municipality of Juárez.The head town was Ciudad Juárez.

1996–2005

Chihuahua lost its tenth district in the 1996 redistricting process. The second district was relocated to the north of the state, with almost exactly the same configuration as in 2005–2017 plan.

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 second district was located in the south of the state, centred on the city of Hidalgo del Parral, an area covered by the 9th district under the 2022 scheme.
