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.

The winner of the competition's top division is recognised as the rugby champion of Asia. The top division, sometimes referred to as the Tri Nations, includes the top three Asian teams each season. Division 1 includes the next four teams and Division 2 includes the next four. Division three is further divided geographically, with each of the West, East and South Central divisions including three teams.

As of 2017, Japan is the most successful team, securing 25 out of a possible 30 titles since 1969. Japan has won all Asia Rugby Championships from 2004 onwards.

The competition was formed as the Asian Rugby Football Tournament in 1969.Chinese Taipei, Hong Kong, Japan, Korea and Thailand contested the inaugural Asian title. Japan were the champions on that occasion.

The tournament was held biennially for the most of its first four decades. It wasn't until 1982 that South Korea became the second team to win the title. The number of teams participating varied from year to year, with as many as 12 teams competing as other Asian teams joined the competition. From 1969 to 1996, there was a single division split into two groups. But in 1998, a second division was introduced as the game began to grow in Asia.

In 2003, a second Asian competition called the Asian Rugby Series was formed. The Asian Rugby Series ran alongside the Rugby Championship to help determine divisional allocations for the Asian Rugby Championship. With more teams competing, a third division was added to the Rugby Championship in 2004. The dual competitions ran until 2007.
