The Stanford 20/20 was a short-lived cricket tournament in the Caribbean island of Antigua. It was held first in July and August 2006 in the West Indies at the Stanford Cricket Ground, St. John's, Antigua and Barbuda, and then again in the same place in 2008. It was a variety of the popular Twenty20 format, which had been first introduced in English cricket in 2003. The tournament was separate to the Stanford Super Series, which was held in late 2008.
