2016 Cup of Nations (rugby union)

The 2016 Cup of Nations was the fourth Cup of Nations rugby union tournament since its creation in 2011. The tournament returned to Hong Kong, reprising its name as the Hong Kong Cup of Nations. The tournament acted as a year ending tournament for "up and coming" tier 3 teams from different continents, providing greater preparation for teams to play in their regional competitions, especially with the 2016 participants aiming to qualify for the 2019 Rugby World Cup or to make the Rugby World Cup global repechage in November 2018.

The four competing teams were hosts Hong Kong, reigning champions Russia, Zimbabwe and Papua New Guinea, who were new to the tournament. Russia successfully defended their title, winning the competition with 14 points.

 * Win = 4 points
 * Draw = 2 points
 * Loss = 1 point
