The One-Day Cup is a 50-over round-robin competition featuring the 18 first-class counties who contest the four-day County Championship.
It was first played in 2014, replacing the ECB 40, which saw each team allocated 40-over innings per match. The organisers increased the number of overs to 50 to bring it in line with one-day internationals.
The One-Day Cup is the latest 50-over tournament to be organised by the ECB, following on from the likes of the Benson & Hedges Cup and Friends Provident Trophy.
The One-Day Cup will be played at a variety of venues across the country. The final was held at Lord's until 2020, when it was moved to Trent Bridge.
The One-Day Cup has found a regular space in the calendar, usually starting on the first week of August and running into the middle weekend in September.
The 2023 One-Day Cup began on the 1st August with the final taking place on 16th September.
The dates for the 2024 edition have yet to be released.
Selected games from the One-Day Cup are broadcast on Sky Sports Cricket.
The 18 counties are separated into two divisions of nine teams, Group A and Group B, with the teams playing each other once in a round-robin format.
Each group winner progresses straight to the semi-finals, while the teams who finish second and third advance to the quarter-finals, with the runner-up in Group A hosting third in Group B and vice-versa.
The victors then face the two group winners before the winners of each semi-final go on to play in the final.
Leicestershire were crowned One-Day Cup champions for the first time in 2023 as they beat Hampshire in a dramatic final at Trent Bridge.
Batting first, the Foxes scored 267-7 from their 50 overs, with Harry Swindells scoring an unbeaten century.
Hants were on course to chase down their target at the midway point of their innings, but an inspired fightback from Leics' bowlers saw the Foxes triumph by just two runs off the final ball of the match.
Remarkably, Leicestershire's victory saw them become the ninth different county to win the One-Day Cup since its inception in 2014.
Durham were the inaugural champions, with Gloucester (2015), Warwickshire (2016), Nottinghamshire (2017), Hampshire (2018), Somerset (2019), Glamorgan (2021) and Kent (2022) taking the honours.
Surrey and Hampshire have each appeared in three finals, but only the latter, in 2018, have lifted the title.
Warwickshire's Ed Barnard was the leading run-scorer in the 2023 One-Day Cup, scoring 616 runs from his nine innings at an average of 77.00.
Somerset batter Andrew Umeed compiled only three runs less than Barnard, with 613 from eight knocks, while Gloucestershire youngster Ollie Price was third on the 2023 runscorer charts with 575 from ten innings.
Warwickshire seamer Oliver Hannon-Dalbt took the most wickets in 2023, claiming 24 scalps in nine matches at a miserly average of 13.40.
Veteran Chris Wright weighed in with 18 wickets, including two in the final, for champions Leicestershire, the same number as Hampshire medium-pacer Ian Holland.
