The 2019 Vitality Blast is the 2019 season of the t20 Blast, a professional Twenty20 cricket league that was played in England and Wales. It was the second season in which the domestic T20 competition, run by the ECB, has been branded as the Vitality Blast due to a new sponsorship deal. The league consisted of the 18 first-class county teams divided into two divisions of nine teams each with fixtures played, slightly later than usual, between July and September. Finals Day took place at Edgbaston Cricket Ground in Birmingham on 21 September 2019. Worcestershire Rapids were the defending champions.
