The 1877–78 Scottish Cup – officially the Scottish Football Association Challenge Cup – was the fifth season of Scotland's most prestigious football knockout competition. For the first time, over 100 teams took part in the competition which began with the first round on 22 September 1877. The cup was won by Vale of Leven for a second time after they defeated Glasgow club 3rd Lanark RV 1–0 in the final on 30 March 1878. Heart of Midlothian and Hibernian were drawn to face each other in the first round in what would be the first competitive Edinburgh derby. Hibernian won 2–1 after a replay.
