The 2019 Women's Cricket Super League, or 2019 Kia Super League for sponsorship reasons, was the fourth and final season of the Women's Cricket Super League (WCSL), the semi-professional women's cricket competition in England and Wales. The competition, run by the England and Wales Cricket Board (ECB), consisted of six franchise teams playing in a Twenty20 format. The tournament was scheduled to be replaced by the Women's Hundred and a new regional domestic structure from the next season, although the full implementation of this was delayed due to the COVID-19 pandemic. Surrey Stars were the defending champions. Western Storm defeated Southern Vipers by 6 wickets to win the 2019 title.
Six teams competed for the T20 title from 6 August to 1 September 2019. The six teams played each other twice in a round robin format. The 2nd and 3rd team played the semi-final while the top team directly went to the final. Both semi-final and final were held on Finals Day at the County Ground, Hove. Teams received 4 points for a win and a bonus point if their run rate was 1.25 times that of their opposition.
