Hafey coached the Swans for three seasons from 1986-1988, his fourth and final senior coaching role after an illustrious career at Richmond, Collingwood and then Geelong.
He guided the Club to top four finishes in his first two seasons at the helm.
Sydney Swans CEO Andrew Ireland said that Hafey made an important contribution to the Club.
“Tom will be remembered as one of the greatest coaches in AFL history, and while at the helm for three seasons, he certainly made his mark at the Swans at an important time,” he said.
“He has been an iconic figure in the game and his passing will be felt by a great many across the industry.
“On a personal level, I was fortunate to be coached by Tom during my career at Collingwood, including the 1977, 1979 and 1980 Grand Finals.
“He was an outstanding mentor and a great motivator who demanded the highest level of professionalism from his players," Ireland said.
