EuroLeague

The EuroLeague is a European men's professional basketball club competition. The league is widely recognised as the top-tier and the most prestigious men's basketball league in Europe. The league consists of 20 teams, of which 16 are given long-term licences and wild cards, making the league a semi-closed league. The league was first organized by FIBA in 1958, subsequently by ULEB in 2000 and then solely by Euroleague Basketball.

The competition was introduced in 1958 as the FIBA European Champions Cup (renamed the FIBA EuroLeague in 1996), which operated under FIBA's umbrella until Euroleague Basketball was created for the 2000–01 season. The FIBA European Champions Cup and the EuroLeague are considered to be the same competition, with the change of name being simply a re-branding. From 2010 to 2025, it was sponsored by Turkish Airlines.

The EuroLeague is one of the most popular indoor sports leagues in the world, with an average attendance of 10,383 for league matches in the 2023–24 season. This was the fifth-highest of any professional indoor sports league in the world (the highest outside the United States), and the second-highest of any professional basketball league in the world, only behind the National Basketball Association (NBA).

The EuroLeague title has been won by 22 clubs, 15 of which have won it more than once. The most successful club in the competition is Real Madrid, with 11 titles while CSKA Moscow follow with 8 and Panathinaikos with 7. The latter is also the competition's most successful club during its modern era since 2000 with 6 trophies, while Virtus Bologna was the first ever winner in 2000–01.

Maccabi Tel Aviv was the competition's last ever champion during the FIBA period which was ended in 2001. Until then FIBA had organised 44 editions with Real Madrid also being the most decorated club during the FIBA era (1958–2001) with 8 titles.
