The ICC World Twenty20 Qualifier is an international Twenty20 cricket tournament run under the auspices of the International Cricket Council. The tournament serves as the final qualifying event for the ICC World Twenty20 for associate and affiliate members. The first edition was held in 2008, with only six teams. This was increased to eight teams for the 2010 tournament and to 16 teams for the 2012 and 2013 editions, but reduced to 14 for the 2015 edition. Currently, the top six finishers in the qualifier move on to the ICC World Twenty20 tournament. Ireland are the most successful team, having won three tournaments (including one shared with the Netherlands) and qualified for the World Twenty20 on every occasion the tournament has been played.
