The Women's Twenty20 Cup, known for sponsorship reasons as the Vitality Women's County T20, is a women's Twenty20 cricket competition organised by the England and Wales Cricket Board. Until the end of the 2019 season, teams were organised in tiered divisions, with a national winner; since, teams have been organised into regional groups. As teams competed in regional groups in 2022, with no national finals, there was no overall winner. The last national champions are Warwickshire, who won the 2019 competition. The most successful side in the history of the competition is Kent, with 3 wins.
