| Renfrewshire Derby | |
Since the sides first met in 1882,[5] the fixture has grown in significance over the years, due in part to the demise of other Renfrewshire football clubs, and is one of the most hotly contested derbies in Scotland today. Although both sides have regularly competed at the same level of Scottish football, recent years have seen St Mirren competing in the Scottish Premiership, with Morton competing in the lower leagues. However, the annual Renfrewshire Cup, a regional cup competition turned pre-season friendly, generally ensures that there is at least one Renfrewshire Derby a year.
In the 2014–15 season, St Mirren were relegated from the SPFL Premiership, and Morton were promoted from Scottish League One, meaning that the two sides met in league action for the first time in 15 years. As of 6 August 2016, it was confirmed that Morton have gone 6238 days without a competitive win against St Mirren. In November 2016 Morton recorded a 3–1 victory over St Mirren, their first in the league in 17 years.[6]
The rivalry sees a large amount of animosity between the two sets of fans.[7] [8]
