A Twenty20 International (T20I) is a form of cricket, played between international members of the International Cricket Council (ICC), where each team faces a maximum of twenty overs. These matches hold top-class status and are the highest T20 standard. The game is played under the rules of Twenty20 cricket. Starting from the format's inception in 2005, T20I status only applied to Full Members and some Associate Member teams. However, in April 2018, the ICC announced that it would grant T20I status to all its 105 members from 1 January 2019.

Cricket is a bat-and-ball game that is played between two teams of eleven players on a field at the centre of which is a 22-yard (20-metre) pitch with a wicket at each end, each comprising two bails balanced on three stumps. Two players from the batting team stand in front of either wicket, with one player from the fielding team bowling the ball towards the striker's wicket from the opposite end of the pitch. The striker's goal is to hit the bowled ball and then switch places with the nonstriker, with the batting team scoring one run for each exchange. Runs are also scored when the ball reaches or crosses the boundary of the field or when the ball is bowled illegally.
