The New Firm is the term used, hailing from the 1980s, to describe the rivalry between Scottish football clubs Aberdeen and Dundee United.

[2][3] The Old Firm have more often than not been the dominant force in Scottish Football, however throughout the 1980s both Aberdeen and Dundee United were more than a match for them, regularly beating them home and away and winning many of the trophies on offer.

However, in the 1994–95 season both sides fought relegation (with United going down), and although Aberdeen won the Scottish League Cup in 1995 and Dundee United the Scottish Cup again in 2010, neither side has managed to be a consistent force for Rangers and Celtic to reckon with, and Aberdeen's league success in 1984–85 is the last time a non-Old Firm club won the Scottish league title.

Since 2010 however, the sides have seen a divergence in fortunes, as Aberdeen capitalised on Rangers' implosion to win the Scottish League Cup in 2014 and finish runners-up behind Celtic for four years running between 2014–15 and 2017–18 (losing three cup finals to the same club in that period), while Dundee United were relegated from the top flight in 2016 having lost the 2014 Scottish Cup Final to a local rival, St Johnstone.

In domestic head-to-head matches, the teams have played each other 246 times, Aberdeen winning 98 compared to United's 79.
