The 1989 Scottish Cup final was played between Celtic and Rangers at Hampden Park on 20 May 1989.
Celtic won the match 1–0, denying Rangers a domestic treble. The only goal came when Joe Miller capitalised on a defensive error and slotted the ball past Rangers' goalkeeper.[1]
This was the last Old Firm Scottish Cup final for 10 years until 1999.
While less than 50% of the all-time record crowds at Hampden, the attendance of just over 72,000 has become a landmark figure as no match in Scotland has come close to matching it since, owing to subsequent stadium modernisation which left no venue with a greater capacity.[2]
