Europe

Several countries in Europe have their own top professional senior leagues. Many future KHL and NHL players start or end their professional careers in these leagues. The National League A in Switzerland, Swedish Hockey League in Sweden, SM-liiga in Finland, and Czech Extraliga in the Czech Republic are all very popular in their respective countries.

Beginning in the 2014–15 season, the Champions Hockey League was launched, a league consisting of first-tier teams from several European countries, running parallel to the teams' domestic leagues. The competition is meant to serve as a Europe-wide ice hockey club championship. The competition is a direct successor to the European Trophy and is related to the 2008–09 tournament of the same name.

There are also several annual tournaments for clubs, held outside of league play. Pre-season tournaments include the European Trophy, Tampere Cup and the Pajulahti Cup. One of the oldest international ice hockey competition for clubs is the Spengler Cup, held every year in Davos, Switzerland, between Christmas and New Year's Day. It was first awarded in 1923 to the Oxford University Ice Hockey Club. The Memorial Cup, a competition for junior-level (age 20 and under) clubs is held annually from a pool of junior championship teams in Canada and the United States.

International club competitions organized by the IIHF include the Continental Cup, the Victoria Cup and the European Women's Champions Cup. The World Junior Club Cup is an annual tournament of junior ice hockey clubs representing each of the top junior leagues.
