Eurocup Basketball (also known as the ULEB Eurocup and previously known as the ULEB Cup from 2002–2008) is the second-tier level transnational professional basketball competition in Europe. It is the league level that is one level below the Euroleague. It is organized by the Euroleague Basketball Company, which also oversees the first-tier Euroleague competition. It is mainly composed of teams from European domestic national leagues that are part of the ULEB (a French acronym for "Union of European Basketball Leagues"), and that do not have a contract to compete in the Euroleague.
