The 1873–74 Scottish Cup – officially the Scottish Football Association Challenge Cup – was the first season of Scotland's most prestigious football knockout competition. A total of 16 teams from the west of Scotland entered the competition, however only 14 would play a match after two withdrawals. The competition began with the first match between Renton and Kilmarnock on 18 October 1873 and concluded with the final on 21 March 1874. After 16 matches and 38 goals, the inaugural cup was won by Queen's Park who defeated fellow Glasgow club Clydesdale 2–0 in the final.
