2025 Port Adelaide Football Club season

The 2025 Port Adelaide Football Club season was the club's 29th season in the Australian Football League (AFL) and the 155th year since its inception in 1870. The club also fielded its reserves men's team in the South Australian National Football League (SANFL) and its women's team in the AFL Women's (AFLW).

Port Adelaide entered the season off the back of preliminary final defeats to Sydney and North Melbourne in the AFL and AFLW respectively, and a last-place finish in the SANFL. The season marked the 13th and final year of Ken Hinkley's tenure as senior coach of the AFL team. The club announced Hinkley would finish in the role at the end of the season, and be replaced by former Port Adelaide premiership player Josh Carr. Along with Adelaide, the club hosted 12 home AFL games during the season, including a Gather Round fixture against Hawthorn.

In the AFL, the Power suffered from multiple losses in excess of 70 points and finished with 9 wins and 14 losses, the worst result under Hinkley's tenure, and as a result failed to qualify for the finals in 13th place on the ladder. In the SANFL, the Magpies had a slow start to the season though recovered to finish in sixth position and narrowly miss out on finals. In the AFLW, the side was unable to replicate the form that saw them qualify for finals the previous season; they won six of their twelve matches to finish in 10th place and miss out on the top eight by percentage. Forward Gemma Houghton became the first player in league history to kick 100 career goals, registering the achievement with a goal after the siren in the team's final match of the season.
