Mick Gannon (born 2 February 1947 in Dublin) was an Irish football player in the 1970s who played for Shelbourne and for Shamrock Rovers. Gannon was a diminutive but tenacious right-back who enjoyed a long and successful career in the League of Ireland. A skilful attacker, Gannon was on occasion used in midfield, though it was in the number two shirt that he made his international debut, in Liam Tuohy's first game as manager of the Irish national team against Austria in Linz in October 1971. He returned to Shels in January 1981, where he ended his league career.
