The Sri Lanka national rugby union team, known as the Tuskers, represents Sri Lanka in men's international rugby union. The team has yet to make their debut at the Rugby World Cup. They have the longest tradition of organised club rugby in Asia, dating back to 1879, which was just 8 years after the founding of the world's first rugby union in England. They regularly compete in the Asian Five Nations tournament and are currently in Division I. In the 2010 tournament, they made it to the finals beating Chinese Taipei 37 to 7.

The Asia Rugby Championship, or ARC, is an annual rugby union competition held amongst national rugby sides within the Asia Rugby region. The competition was originally known as the Asian Rugby Football Tournament when founded in 1969, and was called the Asian Five Nations from 2008 to 2014.
