The 2023 Women's Twenty20 Cup, known for sponsorship reasons as the 2023 Vitality Women's County T20, was the 14th edition of the Women's Twenty20 Cup, an English women's cricket Twenty20 domestic competition. It was scheduled to take place in April and May 2023, although one matchday was played later due to rain, with 35 teams taking part, organised into eight regional groups.[1][2]
There was no overall winner, with Lancashire, Warwickshire, Gloucestershire, Sussex, Northamptonshire and Somerset winning their individual groups. Middlesex and Kent shared their group title due to rain on their group Finals Day. One group winner was not determined, with the Group 4 Finals Day abandoned due to rain.
