The Stanford 20/20 Tournament is a cricket tournament which was first held in July and August 2006 in the West Indies at the Stanford Cricket Oval, St. John's, Antigua and Barbuda. It is a variety of the popular Twenty20 format first introduced in English cricket in 2003.

This format of the game was devised and made possible mainly by Sir Allen Stanford, a Texan billionaire with Antiguan roots. He has spent many millions of US$ in the hope of achieving his dream of bringing West Indian cricket back to life. 19 teams played in a straight knock-out tournament to try and achieve first place and with it first prize - US$1 million. Twenty-one (21) teams will compete in the 2008 Tournament (the original 19 plus Cuba and the Turks and Caicos Islands).
