The 2016 World Rugby Cup of Nations was the eleventh edition of the World Rugby Nations Cup rugby union tournament, created by World Rugby (formerly IRB).

As with the previous nine tournaments, the competition took place in the Stadionul Naţional de Rugby in Bucharest, Romania.

Due to Georgia's tour of the Pacific Islands in June, the World Rugby Tbilisi Cup did not take place.

Hosts Romania won the title, for the fourth time in five years.

Romania finished with 13 points after beating the Argentina XV in the decisive match.
