The European Aquatics Challenger Cup is a water polo club competition organised by the European Aquatics. It acts as the fourth tier, below the European Aquatics Champions League, European Aquatics Euro Cup and the European Aquatics Conference Cup. GS Apollon Smyrnis of Greece became the first champions, defeating CN Terrassa of Spain in the final. From 2024, after LEN was renamed to European Aquatics, the new name is the European Aquatics Challenger Cup.
