The Australian Football League's 2006 finals series took place between the teams that finished in the top eight in the 2006 AFL season. It began on the weekend of 8 September 2006 and ended with the 110th AFL Grand Final at the Melbourne Cricket Ground on 30 September 2006. The winner, West Coast Eagles, was crowned champion of the AFL after defeating Sydney by one point.
Eight teams qualified for the finals by finishing in the top eight of the premiership ladder.
With the top eight race effectively ending several rounds before the end of the season, the push for the final two positions in the top four heated up as all six teams below West Coast and Adelaide were vying for the crucial "double chance" with only a few rounds left. With wins in the final round, Fremantle and Sydney secured the "double chance" making it the first time in the game's history where the top four positions did not consist of a single Victorian team.
