The LEN Women's Challenger Cup is a water polo club competition organised by the Ligue Européenne de Natation (LEN).

It acts as the third tier, below the LEN Women's Champions League and the LEN Women's Euro Cup.

[1][2] The Women's Challenger Cup was first mentioned on the 7 February by Stavroula Kozompoli.

In a similar fashion to the men's Tournament, the competition was inaugurated with the goal of creating more chances for smaller Water Polo nations to improve.

A year before the women's counterpart started, LEN formally announced they would create a Men's LEN Challenger Cup, starting in the 2022–23 season.
