The 2025–26 European Aquatics Champions League is the 63rd edition of European Aquatics's premier competition for men's water polo clubs, and the 15th edition since being rebranded from the Euroleague to the Champions League. The season begins on 19 September 2025 and ended on 13 June 2026 with the Final Four.
This will be the third straight season under the new format, however, this season will witness a change in slot allocation, with only the top two from domestic leagues being allowed to take part.
The winners of the European Aquatics Champions League automatically qualify for next season's edition (if they choose to enter) and also qualify for the 2026 Super Cup.
FTC-Telekom are the defending champions.
