C.D. Guadalajara

Club Deportivo Guadalajara S.A de C.V. (Spanish pronunciation: [ˈkluβ ðepoɾˈtiβo ɣwaðalaˈxaɾa];), nicknamed "Chivas" (English: Goats) and simply known as Guadalajara or internationally as Chivas de Guadalajara, is a Mexican professional football club based in the Guadalajara metropolitan area, Jalisco. It competes in Liga MX, the top division of Mexican football. The club was founded in 1906 as Unión Football Club, then changed its name to Guadalajara Football Club in 1908, and then changed to its current name in 1923. Guadalajara was one of the founding members of the Liga Mayor in 1943 (currently Liga MX), which was the first professional football league created in Mexico, and is one of seven teams that have never been relegated.

Guadalajara have played their home matches at Estadio Akron in Zapopan since 2010, having previously played at Estadio Jalisco. Guadalajara is the only football club in Mexico that does not sign foreign players unless they are of Mexican descent. The team has historically relied on home-grown (cantera) players and has been the launching pad of many internationally successful players, including Javier Hernández, Carlos Vela and Carlos Salcido, among others.

Chivas is one of Mexico's most successful teams with 12 league titles, and holds the league record for the longest winning streak at the beginning of a season, with 8 consecutive wins in the 2010 Torneo Bicentenario. Internationally, Guadalajara has won two CONCACAF Champions Cup/League titles, and is the best Mexican side to compete in Copa Libertadores having reached the semifinals twice (2005 and 2006) and being runner-ups in the 2010 edition.

According to a 2016 study of preferred football clubs Guadalajara is the most popular team in Mexico, with 44.1% of supporters in the country. In 2020, Forbes estimated that the club was the most valuable of the league, ranking sixth overall in the Americas, worth approximately $311.5 million.
