The 2007 ICC World Twenty20 was the inaugural Twenty20 International cricket world championship, contested in South Africa from 11 to 24 September 2007. Twelve teams took part in the thirteen-day tournament—the ten Test-playing nations and the finalists of the 2007 WCL Division One tournament: Kenya and Scotland. India won the tournament, beating Pakistan in the final.

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.
