The 2005 AFL season was the 109th season of the Australian Football League (AFL), the highest level senior Australian rules football competition in Australia, which was known as the Victorian Football League until 1989. The season featured sixteen clubs, ran from 24 March until 24 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 Sydney Swans for the fourth time, after they defeated West Coast by four points in the AFL Grand Final. It was the club's first premiership since it won the 1933 premiership as South Melbourne, and ended a 72-year premiership drought which stands as the longest in league history.
