The 2014–15 Turkish Airlines Euroleague was the 15th season of the modern era of Euroleague Basketball and the fifth under the title sponsorship of the Turkish Airlines. Including the competition's previous iteration as the FIBA Europe Champions Cup, this was the 58th season of the premier competition for European men's clubs.
The rest of the teams places were allocated from a list of 28 teams given a B-Licence ranked according to their European national basketball league rankings over the last year. 13 teams were given both an A-Licence or C-Licence and a B-Licence. When a country ranking spot had already been assigned to an A-Licence team, the assignation jumped to the next country appearing in the ranking, and their league was not granted an additional place in the competition. At least the first 9 of the remaining 16 teams were given places in the regular-season, and the next 6 were given places in the qualifying competition.
If the Eurocup champion was qualified by receiving a B licence or some team with it resigned from the competition, a wild card had to be given by the Euroleague.
The Euroleague had the right to cancel an A licence for one of the following reasons:
The club had the lowest ranking of all clubs with an A Licence, according to the Club Ranking.
The club had ranked among the clubs placed in the bottom half of the national championship final standings.
The club had financial problems.
In Spanish League, when the champion and/or the runner-up of the league were teams without an A licence. In that case, the A licence club with the lowest position would play in Eurocup in the next season. If that happened three times in five years, the A licence of the club would have been cancelled.
B licences could be given to every team without an A licence. If in the allocation appeared a team with A licence, the next team in the criteria would receive the B licence, which qualified directly to the Regular Season.
The participating teams for the season were announced on June 25, 2014. The labels in the parentheses show how each team qualified for the place of its starting round (TH: Euroleague title holders):
