2011 Port Adelaide Football Club season

Domenic Cassisi was confirmed to retain the captaincy for the 2011 season as part of a seven-man leadership group.

Port Adelaide recorded its worst ever season in the AFL, with only three wins in the year, against in Round 4,  in Round 10, and  in Round 24. They also became the first team to lose to expansion club after Port's Justin Westhoff missed a kick after the siren that would have won the game for Port Adelaide. Port narrowly avoided last place on the ladder and the wooden spoon with their final round win over Melbourne, which lifted them above on the ladder.
