FREMANTLE president Steve Harris will step down from his position at the end of October.
Harris spoke at a pre-game function ahead of the Dockers' clash with Adelaide at Domain Stadium on Sunday.
"It has been a great honour and a privilege to serve as president of the Fremantle Dockers during what has been a dynamic period of growth, development and progress for the club," Harris said.
"During the past seven years I have been very fortunate to have the support and guidance of an outstanding board of directors, whose collective talents and diverse range of views have helped position the club where it is today."
Harris announced that Dale Alcock would take over as Fremantle president in a move that had been planned since mid-2014.
"The move to appoint Dale as the next president of the Fremantle Dockers has been a well-planned and measured process that has been discussed by the board throughout the past 18 months," Harris said.
"Our aim during that time has been to ensure a smooth transition for the incoming president, which was important for the governance of the club.
"Given that my current term on the board ends on October 31 and that there is such a high quality individual as Dale Alcock available to take on the role, the time is right for me to step aside.
"I'm also leaving at a time when I can say with great confidence and a sense of pride that we have the strategy, resources and people in place to give the club, our players and our members the best opportunity at achieving success."
Alcock has been on the board since 2011. He is the managing director of construction, property and finance firm ABN Group.
The Dockers are set to move into their brand new training and administration facility in Cockburn in March next year.
Alcock has chaired the Dockers' facilities sub-committee, which has overseen the development of their future base. The club will also move to play its home games at the new Perth Stadium in 2018.
AFL Commission chairman Mike Fitzpatrick congratulated Harris for his contribution to the Dockers.
"Steve has left the Fremantle Football Club in an extremely strong position with his work leading an excellent board over the last seven years," Mr Fitzpatrick said.
"Their new training and administration facility will be one of the best in the competition and the club has built itself up to be a strong financial presence in our game with a passionate and loyal fan base.
"On behalf of the AFL Commission, we thank Steve for his contribution and wish him well for the future."
