2015 Cup of Nations (rugby union)

The 2015 Cup of Nations was the third Cup of Nations tournament, but the first held outside the United Arab Emirates. Unlike 2011 and 2012, the Cup of Nations was staged in Hong Kong at the Hong Kong Football Club Stadium from November 13 to 21. The tournament acted as a year ending tournament for tier 3 teams from different continents and provides greater preparation for teams to play in their regional competitions, especially this year participants who aim to qualify for the 2019 Rugby World Cup haven failed to qualify for the 2015 Rugby World Cup.

The four competing teams were hosts Hong Kong, who won the tournament in 2011, Zimbabwe who competed in 2012, while Portugal and Russia are new to the tournament having not competed in either of the 2015 World Rugby Tbilisi Cup or 2015 World Rugby Nations Cup.
