Round and draw dates
The schedule of the competition was as follows.

Draw
The draw was held on 7 July 2023 in Barcelona, Spain.

The 20 teams were drawn into two groups of 10, with the restriction that teams from the same league could not be drawn against each other, except when there were more than two teams from the same league participating in the regular season. For the draw, the teams were seeded into 10 pots, in accordance with the Club Ranking, based on their performance in European competitions during a three-year period and the lowest possible position that any club from that league can occupy in the draw is calculated by adding the results of the worst performing team from each league.

The fixtures were decided after the draw, using a computer draw not shown to public, with the following match sequence:

Note: Positions for scheduling do not use the seeding pots, e.g., Team 1 is not necessarily the team from Pot 1 in the draw.

There were scheduling restrictions: for example, teams from the same city in general were not scheduled to play at home on the same round (to avoid them playing at home on the same day or on consecutive days, due to logistics and crowd control).

Regular season
The regular season started on 3 October 2023 and ended on 7 February 2024. In each group, teams played against each other home-and-away in a round-robin format where only six teams advanced to the playoffs. Moreover, the top two teams in each regular season group received first round playoff byes, skipping the eighthfinals to be placed directly into the quarterfinals. At the tail end of the standings, four teams from each group were eliminated after the regular season. Alongside 17 returning teams from last season, Wolves made its debut appearance, and Aris Midea and Beşiktaş Emlakjet welcomed back to the EuroCup eight years later.

Playoffs
In the playoffs, teams played against each other in a knockout tournament into four rounds from eighthfinals to finals. At the end of the regular season, the six teams from each group with the most wins qualified for the playoffs. The two top teams from each regular season group received a bye and qualified directly to the quarterfinals. The remaining eight qualified teams entered the eighthfinals to compete in a single-game format in which the third-placed teams of each group faced off against the sixth-placed teams of the opposite groups and the fourth-placed teams of each group faced off against the fifth-placed teams of the opposite groups. The four winning teams from eighthfinals entered the quarterfinals to faced off in a single-game format in the home of the two top teams from each regular season group. The higher-placed regular season team in each matchup enjoyed home court advantage in eighthfinals and quarterfinals. From semifinals onwards, teams played in best-of-three series with the first leg and third leg, if necessary, in the home court of the higher-placed regular season team to crown the EuroCup champion.
