The 2013 Australian Football League finals series determined the winner of the 2013 AFL season.
The top eight teams from the home and away season qualified for the finals series.
The top four teams (Hawthorn, Geelong, Fremantle and Sydney) all made the preliminary finals.
Both Carlton and Port Adelaide made the semi-finals, while Collingwood and Richmond lost their respective elimination finals.
Essendon originally finished seventh but were disqualified due to an Australian Sports Anti-Doping Authority (ASADA) investigation into their possible use of un-approved supplements during the 2012 season.
