Club Deportivo Guadalajara S.A. de C.V. often simply known as Guadalajara and their nickname Chivas, is a Mexican professional football club based in Guadalajara, Jalisco. Guadalajara is one of the ten founding members of the Mexican First Division and along with Club América is one of only two teams that have never been relegated to the second-tier division.

Guadalajara is the only football club in Mexico that doesn't allow foreign players to play in their club. The team has constantly emphasized home-grown (cantera) players and has been the launching pad of a few internationally successful players, including Omar Bravo, Javier Hernández, Francisco Javier Rodríguez, Carlos Salcido and Marco Fabián. The team's three colors (red, white, and blue) symbolize "Fraternity, Union, and Sports". The founders of the team adopted the colors that linked them back to their home country, France. Chivas supporters use a flag identical to the French flag to support their team. The team mascot, as well as their nickname, is the goat or chiva.

Chivas is one Mexico's most successful teams and holds the Mexican league record for the longest winning streak at the beginning of a season, with 8 consecutive wins. Internationally, Guadalajara 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 study of preferred football clubs published in April 2016 by Euroamericas Sport Marketing Spain, Guadalajara is the most popular team in Mexico, with 44.2% of supporters in the country.
