The 2007 Cricket World Cup warm-up matches were held prior to the 2007 Cricket World Cup, between 5 March and 9 March 2007. All 16 nations that were qualified to take part in the World Cup participated in a series of matches to prepare, experiment with different tactics and to help them acclimatise to conditions in the West Indies. The warm-up matches were not classified as One Day Internationals by the International Cricket Council (ICC), despite sharing some of main features of this form of cricket, but some of the playing regulations were different from standard internationals in order to allow teams to experiment. For example, the main change allowed for thirteen different players to play in a match – nine players being allowed to both bat and bowl, with two only being able to bowl and two only being able to bat – instead of the eleven players normally allowed.
