Cruz Azul, officially Club de Futbol Cruz Azul, is a professional football club based in Mexico City, Mexico. It competes in the Liga MX, the top division of Mexican football. Because "azul" means "blue" in Spanish, the club has traditionally worn a blue home kit.

A treble in association football is achieved when a club team wins three trophies in a single season. A continental treble involves winning the club's top-level domestic league competition, main domestic cup competition, and main continental trophy. Although winning a second-tier continental trophy has also been described as a continental treble, it is not as widely accepted. A domestic treble involves winning three national competitions—including the league title, the primary cup competition, and one secondary competition, such as a secondary cup or state-level league.
