The second federal electoral district of Coahuila (Distrito electoral federal 02 de Coahuila) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of eight such districts in the state of Coahuila.

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 second region.

Coahuila's second district is one of the country's largest in terms of its surface area. Under the 2022 districting plan, which is to be used for the 2024, 2027 and 2030 federal elections and which gave Coahuila an additional district, it covers 11 municipalities: Cuatrociénegas, Francisco I. Madero, Frontera, Lamadrid, Múzquiz, Nadadores, Ocampo, Sacramento, San Buenaventura, San Pedro and Sierra Mojada. The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the city of San Pedro de las Colonias.

2005–2017

From 2005 to 2017, the district was in the same area as under the 2002 scheme. It comprised the municipalities of Cuatrociénegas, Francisco I. Madero, Frontera, Lamadrid, Múzquiz, Nadadores, Ocampo, San Juan de Sabinas, San Pedro, San Buenaventura and Sierra Mojada. The head town was the city of San Pedro de las Colonias.

1996–2005

Between 1996 and 2005, the district's territory comprised roughly the same municipalities as in 2005–2017: Cuatrociénegas, Francisco I. Madero, Frontera, Lamadrid, Nadadores, Ocampo, Sacramento, San Pedro and Sierra Mojada.
