The 2007–08 ULEB Cup was the sixth season of the second-tier level European professional club basketball competition, the EuroCup, which is organized by Euroleague Basketball S.L. It was also the last season for the competition under the name of ULEB Cup. The EuroCup is the European-wide league level that is one tier below the EuroLeague level. On July 2, 2008, EuroLeague Basketball S.L. and FIBA Europe announced that the competition would be renamed to the Eurocup, starting with the 2008–09 season.
For the first time, 54 teams competed. The Final Eight was held from April 10, to April 13, in Turin, Italy, in the Palavela arena. The trophy was won by the Spanish club DKV Joventut, with the other finalist being another Spanish team, Akasvayu Girona. Dynamo Moscow took third place.
For the first time in its short history, this season's ULEB Cup featured a total of 54 teams, divided into 9 groups of 6 teams. The round-robin group stage was followed by knock-out stages, until the last 8 remaining teams met in the competition's first ever Final Eight tournament. Just as in the previous season, the official broadcast partner of the ULEB Cup was Eurosport. The regular season began in November 2007.
