International rules football (Irish: Peil na rialacha idirnáisiunta; also known as international rules in Australia and compromise rules or Aussie rules in Ireland) is a team sport consisting of a hybrid of football codes, which was developed to facilitate international representative matches between Australian rules football players and Gaelic football players.

The first tour, known as the Australian Football World Tour, took place in 1967, with matches played in Ireland, the United Kingdom, and the United States. The following year, games were played between Australia and a touring County Meath Gaelic football team, Meath being the reigning All-Ireland senior football champions. Following intermittent international tests between Australia and Ireland, the International Rules Series between the senior Australia international rules football team and Ireland international rules football team has been played intermittently since 1984, and has generally been a closely matched contest. The sport has raised interest and exposure in developing markets for Gaelic and Australian football and has been considered a development tool by governing bodies of both codes, particularly by the AFL Commission.

International rules football does not have any dedicated clubs or leagues. It is currently played by men's, women's, and junior teams only in tournaments or Test matches.
