The WSE Champions League is an annual club roller hockey competition organised by the World Skate Europe - Rink Hockey and contested by teams from the top-ranked European leagues.

Since its foundation in 1965, under the name of European Cup, the competition has been dominated by teams from Spain (mainly from Catalonia), Portugal and Italy.

In 2023, along with a renaming back to Champions League, the format was again changed to accommodate 32 teams and two preliminary rounds.

The most successful team is Barcelona, having won a record 22 titles, including eight consecutive between 1978 and 1985.

Barcelona are followed by four other Spanish teams, making Spain the most successful country in the competition, with 44 titles.
