The 2023–24 WSE Champions League is the 59th season of Europe's premier club roller hockey tournament organized by World Skate Europe – Rink Hockey, and the second season under the WSE Champions League branding. Compared to the previous season, the knockout stage quarter-finals will be contested as two-legged fixtures followed by a final-four tournament, scheduled to be played on 11 and 12 May 2024.
FC Porto were the defending champions, having beaten AD Valongo 5–1 in an all-Portuguese 2022–23 final. They were eliminated in the semi-finals by domestic rivals Sporting CP, who went on to beat another Portuguese side in the final (UD Oliveirense, 2–1) and win their fourth title in the competition. This was the second consecutive all-Portuguese final, which was assured after four Portuguese teams – OC Barcelos, UD Oliveirense, FC Porto, and Sporting CP – secured qualification for the final four tournament.
For the 2023–24 WSE Champions League, the associations were allocated places according to their coefficient, which takes into account the performance of each association's representative teams in European competitions between the 2018–19 and the 2022–23 seasons (except for the 2019–20 season, which was discarded due to being interrupted). The coefficient is calculated by dividing the total of points accumulated by the number of participating teams.
The D'Hondt method was applied to the coefficient of each association to determine the number of teams entering in each round:
