Twelve teams contested the league: Aberdeen, Celtic, Dundee, Dundee United, Hamilton Academical, Inverness CT, Kilmarnock, Motherwell, Partick Thistle, Ross County, St Johnstone and St Mirren.

Due to the relegation of Edinburgh-based teams Heart of Midlothian and Hibernian in 2014, this season marked the first time in football history in which a capital city had no representatives in the top league.

The league attempts to balance the fixture list so that teams in the same section play each other twice at home and twice away, but sometimes this is impossible.

The team that finished 12th (St Mirren) was relegated to the Championship, while the champion of that league (Heart of Midlothian) was promoted to the Premiership for the 2015–16 season.

The team that finished 11th in the Premiership (Motherwell) played the winner of the Championship playoffs (Rangers) in two playoff games, with the winner (Motherwell) securing a Premiership spot for the 2015–16 season.
