The CONCACAF Champions Cup, formerly known as CONCACAF Champions League (2008–2023), is an international association football competition organized by CONCACAF as its top continental tournament for clubs from North America, Central America, and the Caribbean. The champions automatically qualify for the FIFA Club World Cup and the FIFA Intercontinental Cup.

The tournament currently uses a knockout format; it had a group stage prior to the 2018 edition. Unlike Europe's UEFA Champions League and South America's Copa Libertadores, the winner of the CONCACAF Champions Cup does not automatically qualify for the following edition of the tournament.

30 clubs have won the competition at least once, with 14 of them having won the title more than once. Mexican clubs have won the title 40 times, the most of any nation in the confederation. The second most successful nation is Costa Rica, with six titles in total, followed by clubs from the United States and El Salvador with three for each country. Club América and Cruz Azul are the most successful club in the competition, winning seven titles each. The most successful non-Mexican club is Deportivo Saprissa of Costa Rica, which has won three titles. The only four teams to successfully defend the title are all Mexican: América, Cruz Azul, Pachuca and Monterrey.

The current champions of the competition are Cruz Azul, who defeated Vancouver Whitecaps FC in the 2025 final.

Currently, each round of competition consists of a two-leg home-and-away series with the winners determined by aggregate goals over both legs. If aggregate goals are equal, the away goals rule is applied. If away goals are also equal, the game goes to an extra time period. If it is still tied, the game is decided through a penalty shoot-out.

Prior to 2018, the tournament had two parts: a group stage held from August to October, and a knockout phase held from March to May of the following year. The group stage consisted of 24 teams playing in eight groups of three teams each, with each team playing the other two teams in its group twice. American and Mexican sides could not be drawn into the same group. The winners of each of the eight groups advanced to the quarterfinals. Each phase of the knockout rounds (quarterfinals, semifinals, finals) consisted of a two-leg home-and-away series with the winner determined by aggregate goal differential. Seeding in the knockout phase was determined by performance during the group stage.

Prior to the 2012–13 season, the competition had involved four groups of four, with one Mexican team and one U.S. team in each group. A preliminary round was used to reduce the number of teams from 24 to 16.

Prior to 2008, the tournament was called the CONCACAF Champions' Cup, but was usually referred to simply as the Champions' Cup. The competition began play in 1962.
