TheEuropean Aquatics Women's Euro Cup, formerly theWomen's LEN Trophy andLEN Women's Euro Cup, isEuropean Aquatics's second-tier competition for women'swater polo clubs. It was first held in 2000 and 2001 as the LEN Women's Cup Winners' Cup.[1] It was contested for many seasons by around 15 teams, which could qualify for it either directly due to high ranking in their domestic league or by being eliminated at certain stages of theChampions' Cup. After the last reformations in the European competitions system by LEN, only four teams contesting for the trophy, coming after elimination at that season'sLEN Euro League quarterfinals stage.Italy'sGifa Palermo,Ortigia,Racing Roma,Imperia,Russia'sShturm Ruza, andGreece'sEthnikos Piraeus are the most successful clubs in the competition with two titles each.[2]
