The European professional basketball club rankings are determined by the results of the professional basketball clubs in the EuroLeague and the EuroCup over the previous three seasons, excluding the competition's qualifying rounds.
The clubs receive two points for a win and one point for a loss, in games of the main stages of the EuroLeague and the EuroCup. Qualifying round results are not taken into account. Clubs also receive 2 bonus points for reaching the Top 16 stage of the EuroCup, 2 bonus points for reaching the last 8 stage, one bonus point for reaching the last 4 stage, and 1 bonus point for reaching the Finals.
In case of a tie, the club with more wins in the last three seasons will rank higher. Should a tie persist, the ranking in the last EuroLeague or EuroCup season will determine the positions.
The top 30 clubs in the current rankings are as follows:
