This is a list of the squads picked for the 2007 Cricket World Cup. This was the ninth Cricket World Cup tournament and was held between 14 March and 28 April 2007. The sixteen teams were asked to announce their final squads by 13 February 2007. Changes were allowed after this deadline at the discretion of the ICCs Technical Committee in necessary cases, such as due to player injury. In order to aid the teams to select the final fifteen, teams were given the option to announce a thirty-man squad by mid-January, with the understanding that the final squad would be picked from within these thirty players. However this was not strictly adhered to—several of England's final fifteen came from outside the initial thirty, for example.
England announced their final 15-man squad at The Oval on 14 February 2007. Jon Lewis was replaced by Stuart Broad on 4 April 2007 to enable him to attend to a personal situation (return home to his wife as she was experiencing complications in the latter stages of her pregnancy).
Ireland named their squad in August 2006, the first country to do so, in order to assist the players in arranging work and training schedules. Irish player Ed Joyce, who turned out for Ireland in qualifying matches, was in England's squad.
Pakistan announced a preliminary squad on 10 January 2007, and the final 15-man squad on 13 February 2007. Both Shoaib Akhtar and Mohammad Asif were included, despite their ongoing doping case, where the Pakistan Cricket Board had first banned them before a tribunal reprieved the two. In a twist of fate, both players were replaced by Mohammad Sami and Yasir Arafat on 1 March due to knee and elbow injuries respectively.
Pakistan had already made one change due to injury: Azhar Mahmood joined the squad in place of Abdul Razzaq, who suffered a knee injury during a practice session on 26 February.
