The 2009 ICC World Twenty20 was the second edition of the Men's T20 World Cup, formerly known as the ICC World Twenty20 that took place in England in June 2009. As before, the tournament featured 12 male teams – nine of the ten Test-playing nations and three associate nations, which earned their places through a qualification tournament. ICC Full member Zimbabwe were expelled from the tournament due to political reasons. Matches were played at three English grounds – Lord's and The Oval in London, and Trent Bridge in Nottingham. The tournament was organised in parallel with the women's tournament, with the men's semi-finals and final being preceded by the semi-finals and final from the women's event. The final took place at Lord's on Sunday 21 June with Pakistan beating Sri Lanka by eight wickets and England beating New Zealand by six wickets in the women's final.

In June 2006, The Daily Telegraph reported that the Marylebone Cricket Club and Surrey CCC had put in a joint bid to host the tournament at Lord's and The Oval.

In December 2007, the ICC provisionally approved a Women's World Twenty20 to run alongside the men's event which, subject to the approval of the ICC's finance and commercial affairs committee, would come into effect for the 2009 tournament in England.

In early January 2008, speculation arose that the tournament could be held elsewhere as the British government have banned Zimbabwe from touring England in 2009. However, it was later confirmed that the tournament would definitely take place in the country.

In April 2008, the third venue was confirmed as Nottingham's Trent Bridge; the 17,500 seater stadium was chosen to hold one of the semi-finals, among other earlier matches. Lord's and The Oval are the two other confirmed venues, with the opening match and final being played at Lord's. Old Trafford Cricket Ground had bid for the third venue, but Trent Bridge was chosen for its closer proximity to the two London grounds.
