The ICC ODI Championship is an international One Day International cricket competition run by the International Cricket Council. The competition is notional in that it is simply a ranking scheme overlaid on the regular ODI match schedule. After every ODI match, the two teams involved receive points based on a mathematical formula. Each team's points total is divided by their total number of matches played to give a rating, and all the teams are ranked in a table in order of rating.

By analogy to cricket batting averages, the points for winning an ODI match are always greater than the team's rating, increasing the rating, and the points for losing an ODI match are always less than the rating, reducing the rating. A drawn match between higher and lower rated teams will benefit the lower-rated team at the expense of the higher-rated team. An "average" team that wins as often as it loses while playing a mix of stronger and weaker teams should have a rating of 100.

As of 8 December 2016, Australia lead the ICC ODI Championship with a rating of 120, while the lowest rated team, Ireland, has a rating of 42.

The championship consists of two separate ranking tables. The ten ICC Full Members that play Test cricket are automatically listed on the main table. The six Associate Members with One Day International status are listed on a secondary table, but are eligible for promotion to the main table by meeting one of the following criteria:

Ireland qualified for the main table following their victories over Pakistan and Bangladesh in the 2007 World Cup. Latest entrant is Afghanistan, by defeating Bangladesh in 2014 Asia Cup. Netherlands and Kenya were also listed on the main table as they previously had permanent ODI status.
