The LEN Women's Champions' Cup 2010/11 is the highest-level competition in women's European club water polo. It involves the champions and other top teams from European national leagues and runs from December 2010 to April 2011. The Final Four (semifinals, final, and third place game) will take place at a neutral site to be determined.

Federation team allocation

Each national federation can enter up to two teams into the Women's Champions' Cup.

• Seeded Federations are the federations who placed a team in the Final Four of the previous' year's competition. In 2009/10, these countries were: Greece (2), Italy, and Russia
• All other federations are unseeded

Federations do not have to enter their top two teams into the Champions' Cup. If they do not think their clubs can be competitive, they can enter teams into the second-tier LEN Cup
