The Cricket World Cup is the international championship of One Day International (ODI) cricket. The event is organised by the sport's governing body, the International Cricket Council (ICC), every four years, with preliminary qualification rounds leading up to a finals tournament. The tournament is one of the world's most viewed sporting events and considered as the "flagship event of the international cricket calendar" by the ICC. It is widely considered the pinnacle championship of the sport of cricket.

A world cup is a global sporting competition in which the participant entities – usually international teams or individuals representing their countries – compete for the title of world champion. The events most associated with the concept are the FIFA World Cup for association football, along with the ICC Men's Cricket World Cup for cricket, both of which are widely known simply as "the World Cup." However, there are a number of notable popular team sports competitions labeled "world cups", such as the Rugby World Cup, Rugby League World Cup, and the Hockey World Cup.
