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.

Rugby union football, commonly known simply as rugby union or more often just rugby, is a close-contact team sport that originated at Rugby School in England in the first half of the 19th century. Rugby is simply based on running with the ball in hand. In its most common form, a game is played between two teams of 15 players each, using an oval-shaped ball on a rectangular field called a pitch. The field has H-shaped goalposts at both ends.
