Collingwood president Jeff Browne will step down at the end of the year.
Browne announced his departure via a letter to Collingwood fans, citing a desire to focus on his health.
He has been at the helm of the AFL club since 2021, but won't seek re-election.
"It is with mixed feelings that I announce I will complete my three-year term as president of the Collingwood Football Club and will not seek re-election at the upcoming AGM to be held on December 16 this year," Browne said.
"Over the past few years, we have done an extraordinary amount of work together at Collingwood, and I am grateful to have been able to play a role in our club's achievements on and off the field.
"I do want to assure you I am healthy and in remission from my cancer diagnosis last year, but as you would understand, the demands of being president are significant and carry a heavy responsibility and workload.
"I do need some more time to devote to maintaining my health and I am confident that the next president will bring their own style and lead the club admirably and with great distinction."
Under Browne's watch, Collingwood won the 2023 premiership with coach Craig McRae, and also implemented the recommendations of the Do Better report regarding systemic racism at the club.
Browne had wanted to leave with Collingwood in a strong position, and reiterated that in his letter.
"As I step away, I do so knowing that the club is in a very healthy position - a much better position to that I found at the beginning of my journey," he said.
But Browne leaves when things are far from settled at the AFL powerhouse.
The Magpies missed finals this year, and former football boss Graham Wright did not return from an in-season overseas sabbatical.
Wright is set to be announced as current Carlton CEO Brian Cook's deputy before taking the reins full-time via a handover plan.
