Duncan MacKay (14 July 1937 – 23 December 2019) was a Scottish footballer who played for Celtic, Third Lanark, Melbourne Croatia, Perth Azzurri and the Scotland national team.
MacKay opted to move to Australia at this juncture, joining Melbourne Croatia of the Victorian State League.
He helped the side to the State title in 1968 and several Dockerty Cup triumphs but left when Croatia were suspended following crowd disturbances in 1972.
He returned to Scotland and joined junior club St Anthony's as a player-coach for two years before deciding upon a second stint in Australia.
After playing for Perth Azzurri between 1974 and 1977 he coached with South Melbourne[4] and Croatia (now known as Essendon Lions), the latter as Captain-Coach.
