The 2019 Vitality Blast was the seventeenth edition of the T20 Blast currently known as the Vitality Blast, a professional Twenty20 cricket league that was played in England and Wales which was 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.
On 7 August 2019, in the match between the Leicestershire Foxes and the Birmingham Bears, Leicestershire's Colin Ackermann took seven wickets for eighteen runs. These were the best bowling figures in a Twenty20 cricket match.
The top four teams from each division will qualify for the knockout stage.
