The 2003 AFL season was the 107th season of the Australian Football League (AFL), the highest level of senior Australian rules football competition in Australia, which was known as the Victorian Football League until 1989. The season featured sixteen clubs, ran from 28 March until 27 September, and comprised a 22-game home-and-away season followed by a finals series featuring the top eight clubs.
The premiership was won by the Brisbane Lions for the third time and third time consecutively, after it defeated Collingwood by 50 points in the AFL Grand Final.
