World Rugby Pacific Nations Cup

The Pacific Nations Cup is an international rugby union competition held between three Pacific states: Fiji, Samoa and Tonga. The 2019 edition of the tournament also included the national teams of Canada, Japan and United States. First held in 2006, the tournament is intended to strengthen the Tier 2 rugby teams by providing competitive test matches in a tournament format.

Previously, Japan participated from 2006 to 2015, New Zealand from 2006 to 2009, Australia from 2007 to 2008, and Canada and the United States from 2013 to 2015. The inaugural tournament was the only one that carried the title of IRB Pacific 5 Nations; from 2007 the competition was known as the IRB Pacific Nations Cup.
