The International Rules Series is a senior men's international rules football competition between the Australia international rules football team (selected by the Australian Football League) and the Ireland international rules football team (selected by the Gaelic Athletic Association). International rules football is played using a set of compromise rules devised by both governing bodies. While the International Rules Series matches use some rules from Australian rules football, the field, ball and uniforms of both teams are derived from Gaelic football.
The competition originated in the 1980s, with four series played in that decade. It was contested annually between 1998 and 2006, and then featured sporadically over next eleven years, with the last series contested in 2017 and no future series scheduled as of September 2024. At the height of its popularity, a series was played over two Test matches in October/November after the completion of the AFL Grand Final and the All-Ireland Football Final, which were both traditionally played in late September, and the winner was the team with the highest cumulative score over both Tests.
