Season 1999–2000 was Hibs' first season back in the top flight of Scottish football, the newly founded Scottish Premier League, after gaining promotion from the First Division in 1999. Hibs re-established themselves well in the top flight, finishing in sixth place. The club also had a good Scottish Cup run, but were disappointingly beaten 2–1 by Aberdeen, who finished bottom of the SPL, in the semi-final at Hampden Park. The season was also memorable for Hibs fans due to a 3–0 win in the "Millennium derby" against Hearts. There was a landmark day towards the end of the season, as the last game on the Easter Road slope was played.

As a club newly promoted to the SPL, Hibs entered at the second round stage of the competition, in which they defeated Clyde in a penalty shootout. This win sent Hibs through to a third round match against Kilmarnock at Rugby Park. In that match, Hibs conceded two early goals, and despite efforts by Pat McGinlay and Kenny Miller, Kilmarnock ran out 3–2 winners.
