The 2020 Bob Willis Trophy was a first-class cricket tournament held in the 2020 English cricket season, and the inaugural edition of the Bob Willis Trophy. It was separate from the County Championship, which was not held in 2020 due to the impact of the COVID-19 pandemic in the United Kingdom. The eighteen county cricket teams were split into three regional groups of six, with the two group winners with the most points advancing to a final held at Lord's. The maximum number of overs bowled in a day was reduced from 96 to 90, and the team's first innings could be no longer than 120 overs.
