The list consists of 29 teams to be joined by seven more who will participate first in the Turkish Airlines Euroleague Qualifying Rounds, for a total of 36 that will start the Eurocup Regular Season. The regular season team list features representation for a total of 19 countries, preserving the Eurocup's status as the most broad-based and inclusive of all European club competitions. The team list will be presented for ratification at the ECA Shareholders Meeting on July 9.

The 2014-15 Eurocup will feature at least six champions and four more runners-up in domestic leagues last season. The 2014-15 field will also feature at least two former Eurocup champions  – Lietuvos Rytas Vilnius (2005, 2009) and Khimki Moscow Region (2012)¬ – as well as 2011 runner-up Cajasol Seville. Clubs also cover the entire map of Europe, from Las Palmas, Spain in the south, to Loimaa, Finland in the North, and Volgograd, Russian Federation in the east.

The teams in the 2014-15 Eurocup Regular Season will be grouped geographically into two regional conferences, divided into six groups of six teams each playing 10 round-robin games. The best four teams in each regular season group will be joined in the Eurocup Last 32 by the eight teams that do not qualify for the Turkish Airlines Euroleague Top 16. They will be divided into eight groups of four, again playing in a round-robin format. From there, the eighthfinals, quarterfinals, semifinals and finals - each consisting of two-game, home-and-away elimination series between pairs of teams – will be played in order to decide the 2014-15 Eurocup Champion, who in turn will qualify for the 2015-16 Turkish Airlines Euroleague.

The seven remaining teams will come from the Turkish Airlines Euroleague Qualifying Rounds.
