The World Rugby Pacific Challenge, formerly the IRB Pacific Rugby Cup, is an annual rugby union football tournament held in Oceania since 2006. It is contested by national 'A' teams (formed from the best locally based players, with most not already on their nations' senior rugby team) from the Asia-Pacific region. The tournament is run by World Rugby (previously IRB) through Oceania Rugby.
The original IRB Pacific Rugby Cup featured two teams from each of the three Pacific Island countries of Fiji, Samoa and Tonga. The competition followed the completion of Fiji's Colonial Cup, Samoa's National Provincial Championship and Tonga's Provincial Championship and provided player development pathway leading into the IRB Pacific Nations Cup.
Since 2011, the tournament has been contested by national 'A' sides, although some matches also featured teams from Super Rugby academies in Australia and New Zealand. Teams from Japan, Argentina and Canada have also joined the tournament to compete with the three Pacific Island countries.
