The Assembly of Syndicated Shareholders of Euroleague Commercial Assets meeting, held on Thursday, June 29, revealed the identities of the 20 teams that will compete in the 2023-24 EuroCup. Alongside 17 returning clubs from last season, the EuroCup will feature debutante Wolves Vilnius and welcome back Aris Thessaloniki and Besiktas Istanbul.
In the coming season, the EuroCup will see clubs from 14 nations, including two each from France, Germany, Italy, Lithuania, Spain and Turkiye. There are two current or former champions (Dreamland Gran Canaria and Joventut Badalona), two more runners-up (Turk Telekom Ankara and Aris), and three more past semifinalists (Cedevita Olimpija Ljubljana, Dolomiti Energia Trento and Prometey Slobozhanske).
Aris has played seven previous seasons in the EuroCup and reached the final in 2006. This season will mark Besiktas's 10th in the EuroCup; its high-water mark was the quarterfinals in 2008. Both teams last competed in the competition during the 2015-16 season. Wolves was founded in 2022 and made its first appearance in international competition last season in the European North Basketball League.
The assembly also approved a new postseason format, which includes best-of-three series in the semifinal and final phases, or the new 2023-24 EuroCup season.
