Cruz Azul

Club de Futbol Cruz Azul S.A. de C.V., commonly referred to as Cruz Azul, is a professional football club based in Mexico City, Mexico. It competes in Liga MX, the top tier of Mexican football. Founded in 1927 in Jasso, Hidalgo, the club officially moved to Mexico City in 1971, where it had already registered a great presence and activity since its beginnings. Estadio Azteca, the nation's largest sports venue, served as their home venue until 1996, when they moved to Estadio Ciudad de los Deportes, which was renamed Estadio Azul. After 22 years, the team returned to the Azteca following the conclusion of the 2017–18 Liga MX season. Its headquarters are in La Noria, a suburb within Xochimilco in the southern part of Mexico City.

Domestically, the club has won nine league titles, four Copa MX, three Campeón de Campeones, and holds a joint-record with one Supercopa de la Liga MX and one Supercopa MX. In international competitions, the club's six titles makes it the second-most successful club in the history of the CONCACAF Champions Cup/Champions League, the most prestigious international club competition in North American football. Cruz Azul also holds numerous distinctions, including being the club with the most league runner-up finishes (12), the first CONCACAF team to reach the final of the Copa Libertadores—the most prestigious club competition in South American football—losing on penalties to Boca Juniors in 2001, achieving a rare continental treble in the 1968–69 season by winning the Primera División, Copa México and CONCACAF Champions' Cup, becoming the first CONCACAF club and third worldwide to accomplish this feat, and becoming the first club worldwide, and one of only five, to have won the continental treble twice.

In its 2014 Club World Ranking, the International Federation of Football History & Statistics placed Cruz Azul as the 99th-best club in the world and the third-best club in CONCACAF. According to several polls published, Cruz Azul is the third-most popular team in Mexico, behind only C.D. Guadalajara and Club América. It is also the second most supported team in its area, Greater Mexico City, behind América and ahead of Pumas UNAM.
