Tayside derby

The Tayside Derby, (also known as the Tayside Trifecta) is a football rivalry based in Tayside. The matches are contested by the three professional clubs in the region: Dundee, Dundee United and St Johnstone.

A match between Dundee and Dundee United, whose grounds are in the same street, is referred to as a Dundee derby. St Johnstone are based in Perth, 20 miles from Dundee.

In seasons where all local derby matches were traditionally held on the same weekend (including at New Year), the Dundee derby would take precedence if all three clubs were in the same league, and any uneven number of Tayside teams would lead to one usually playing Aberdeen, who had no closer rivals geographically.

Followers of the Dundee clubs generally consider their city rivalry as far more important than any relationship with St Johnstone, with Dundee captain Charlie Adam stating in 2021 prior to a Scottish Cup tie with the Saints that there was no such thing as a Tayside derby; opposing goalkeeper Zander Clark did not refute this outright but highlighted the increased travelling support typically brought to each ground for matches due to the close distance between Perth and Dundee, bringing more local interest into league fixtures particularly in seasons where the Dundee clubs are in different divisions and no city derbies are played.

Between them, the three clubs have won thirteen major trophies (as well as finishing runners-up/beaten finalists 26 times across the three competitions), with St Johnstone's three triumphs all the most recent, but they are still behind the Dundee clubs who have each won four cups and one national league championship.

In the season following their title wins, the Dundee clubs each progressed to the semi-final stage of the European Cup (Dundee in 1962–63, United in 1983–84). Dundee also reached the semi-finals of the 1967–68 Inter-Cities Fairs Cup, while Dundee United were runners-up in the 1987 UEFA Cup Final. St Johnstone have never made a major impact in European football, although they qualified for Europe six times between 2014 and 2021, more than either Dundee club managed in the 21st century.

All three clubs have endured spells in the second tier, but St Johnstone are the only club to have dropped into the third tier for a short period. Between them, they have won the second tier championship 14 times, and have lifted the minor Scottish Challenge Cup on four occasions up to 2017–18.

Up to and including season 2024–25.
