Baron-Hay, who will leave the Swans at the end of the year after six years at the helm, said it had been a difficult decision to make.
“I’ve always considered it a privilege to have been part of this club and I will leave with many fond memories and friendships made,” he said.
“I know I will miss it, especially the people who have made it very special.
“Our football club has a proud history that spans 135 years, and over time people come and go,” he said.
“When players, coaches and administrators come to the club we all seek to make a difference and a contribution – I’m no different. It’s a bit like a relay and for my part I’ve run my leg as best and as hard as I can.
“Come year’s end it will be time to pass the baton on to someone else to take up the running.”
Baron-Hay, 46, joined the Swans in 2003 after a career in the financial services industry. A Perth native, he played for Claremont in the WAFL.
Swans president Richard Colless described Baron-Hay's six years at the club as an extraordinary time.
“Myles has made a major contribution to the fabric and culture of our Club during this time and we are all the better for his involvement,” Colless said
Baron-Hay had no firm plans for his future, apart from spending time with his family, but he told the Swans board of his resignation to give the club time to find a successor.
“In the meantime, our absolute focus from a football perspective is on the balance of this season – we believe we can make the finals – and from a commercial perspective there is much to do in planning next year,” he said.
