The 2021 Vitality Blast was the nineteenth edition of the T20 Blast currently known as the Vitality Blast, a professional Twenty20 cricket league played in England and Wales. run by the England and Wales Cricket Board (ECB), that was branded as the Vitality Blast due to the tournament's sponsorship deal.

In June 2021, Samit Patel, playing for the Notts Outlaws, became the first English player to do the double in T20 cricket of taking 250 wickets and scoring 5,000 runs.

In July 2021, Derbyshire's match against Essex in the 2021 County Championship was abandoned before the start of day two due to a positive COVID-19 case in the squad. As a result, Derbyshire's final two T20 Blast group-stage games, against the Northants Steelbacks and the Yorkshire Vikings, were also cancelled. Therefore, the North Group qualifications were decided based on an average points per completed match basis.

Following matches completed on 9 July 2021, the Notts Outlaws were the first team to qualify from the North Group for the quarter-finals. On the same day, they were joined by the Kent Spitfires from the South Group. After the matches completed on 16 July 2021, the Yorkshire Vikings from the North Group had qualified, along with Somerset from the South Group. On 17 July 2021, Lancashire Lightning won the Roses Match against the Yorkshire Vikings to qualify from the North Group. On the final day of group stage matches, the Birmingham Bears from the North Group, and the Sussex Sharks and the Hampshire Hawks from the South Group had all qualified for the quarter-finals.

In the first quarter-final match, the Sussex Sharks beat the Yorkshire Vikings to become the first team to reach Finals Day. The Hampshire Hawks reached the Finals Day, after they knocked out defending champions the Notts Outlaws in the second quarter-final match. Somerset became the third team to reach Finals Day, after they defeated the Lancashire Lightning in their quarter-final match.

On Finals Day, Somerset beat Hampshire Hawks by two wickets in the first semi-final to advance into the final. In the second semi-final, Kent Spitfires beat the Sussex Sharks by 21 runs to advance.
