The Royal London One-Day Cup 2021 tournament will be a limited-overs cricket competition that forms part of the 2021 domestic cricket season in England and Wales. Matches will be contested over 50 overs per side, having List A cricket status, with all eighteen first-class counties competing in the tournament.
The tournament is contested amongst all eighteen first-class counties. The counties are divided into two groups- the North Group and the South Group. The group stage of the tournament is followed by knockouts. The current defending Champions of the Royal London One day Cup is Somerset.
The tournament is scheduled to start on 22 July 2021, with the final taking place on 19 August 2021 at Trent Bridge in Nottingham. Somerset is the defending champions winning the 2020 tournament with no tournament taking place in 2020 due to the COVID-19 pandemic.
|North Group||South Group|
Based on a rough North-South geographical division, the 18 counties are divided into the two groups - the North and the South Group. Each team plays every other team in the group once during the group stage, thus playing a total of eight matches. Four of the right matches of each team are home games, while the other four are away. The group stage winners progress straight to the semi-finals and the second and third-placed teams in each group will play a play-off against a team from the other group in the quarterfinals, and the winner progresses to one of the semi-final matches.
