Club de Deportes Cobresal or simply Cobresal, is a Chilean football club based in El Salvador, Atacama, a Chilean mining camp, and participates in Campeonato Nacional. The team was founded on 5 May 1979, and the name of the club comes from the local copper mine establishment. Since its inception, the club has played its home games at the El Cobre Stadium, which has a capacity of approximately 20,000 seats, which is almost triple of the 7,000 persons that lives in the village.
During the history of Cobresal, the club has been champion once (2015 Clausura) and achieved one Copa Chile title in 1987, with players like the Chilean legend Iván Zamorano, Rubén Martínez and the club's historic top-scorer Sergio Salgado, footballers that also played in the 1986 Copa Libertadores, until this moment the unique international tournament of the club.
Cobresal's classic rival was Regional Atacama, where both teams disputed the III Region derby, but since the disappearance of that team as a result of financial problems, the team now plays the Copper derby with Cobreloa of Calama.
