The 2011 AFL season was the 115th 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 seventeen clubs, with the newly established Gold Coast Suns, based in Gold Coast, Queensland, playing its inaugural season. The season ran from 24 March until 1 October, 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 Geelong Football Club for the ninth time, after it defeated Collingwood by 38 points in the 2011 AFL Grand Final.
