Gary Mackay (born 23 January 1964) is a Scottish former footballer, who made over 500 league appearances for Heart of Midlothian and also played for Airdrieonians and the Scotland national team.

His most significant act as a Scotland player was to score the winning goal on his debut in a UEFA Euro 1988 qualifying match against Bulgaria in Sofia.

[4] Although this goal did not substantially benefit Scotland, who had already been eliminated, it was of great significance to Ireland, who qualified for the finals as a result of this strike.

After retiring as a player in 1999, Mackay then managed Airdrie for a season, but the club suffered severe financial problems[8] and he was sacked to make way for Steve Archibald during July 2000.

[9] Mackay has since worked as an agent, representing players including Garry O'Connor,[10] Christophe Berra[11] and Lee Wallace.
