澳式足球（Australian rules football，在其风行地区俗称Aussie rules或footy），又称澳大利亚式足球，在中国大陆被更多译为澳大利亚式橄榄球或澳式橄榄球，是一种源自于澳大利亚维多利亚州墨尔本地区的橄榄球类运动。有别于一般的足球运动，澳式足球（就其最高等级的澳大利亚澳式足球联盟规则而言）每队场上十八人，另外各有四名替补球员（interchange players），比赛在板球场或差不多大小的椭圆形草地球场上进行，球场长度可达185米（200码），比起其他规则的足球赛大很多（差不多是英式足球的四倍）。

Australian rules football, officially known as Australian football, also called football, footy, or Aussie rules (and in some regions marketed as AFL after the Australian Football League, the most popular and only fully professional Australian football league in the country), is a sport played between two teams of eighteen players on the field of either an Australian football ground, a modified cricket field, or a similarly sized sports venue. The main way to score points is by kicking the ball between the two tall goal posts. The team with the higher total score at the end of the match wins unless a draw is declared.
