Alianza Fútbol Club, also known simply as Alianza, is a football club based in San Salvador, El Salvador. Founded in 1958, Alianza was almost immediately successful, winning its first championships in the 1966 and 1967 Salvadoran seasons. Even more significantly, Alianza was the first Central American and Salvadoran club to win the CONCACAF Champions' Cup in 1967, and is currently one of only three Salvadoran teams to have done so.
