The 2011 Australian Football League finals series determined the winner of the 2011 AFL season.
The series was scheduled to occur over four weekends in September 2011, culminating with the 115th AFL/VFL Grand Final at the Melbourne Cricket Ground on 1 October 2011.
The top four teams in the eight receive what is popularly known as the "double chance" when they play in week-one qualifying finals.
The bottom four of the eight play knock-out games, in that only the winners survive and move on to the next week.
Games in Victoria are played at the MCG, regardless of the team's usual home ground, if a crowd larger than the seating capacity of Etihad Stadium (53,359) is expected.
