1879–80 Scottish Cup

The 1879–80 Scottish Cup – officially the Scottish Football Association Challenge Cup – was the seventh season of Scotland's most prestigious football knockout competition. With 142 entrants, this season saw the largest number of teams to compete for the trophy since its inception. Three-time defending champions Vale of Leven lost their first match in the competition for four seasons when they were knocked out in the first round, losing 4–3 to rivals Dumbarton. Queen's Park regained the trophy as they won the competition for the fourth time after beating Thornliebank 3–0 in the final on 21 February 1880.
