2012–13 Scottish First Division

The 2012–13 Scottish Football League First Division, also known as the 2012–13 Irn Bru Scottish Football League First Division for sponsorship reasons, was the 19th season of the Scottish Football League First Division and the 107th season of a second-tier football league in Scotland. Partick Thistle were confirmed as 2012–13 champions, on 20 April following their 2-0 win over Falkirk. This was the final season of the First Division under its then format, as it was replaced by the Scottish Championship from the 2013–14 season onwards.

Teams
Ross County were promoted to the Scottish Premier League as champions, while Dunfermline Athletic were relegated from the SPL to this division.

Two sides were relegated from this division at the end of the 2011–12 season. Queen of the South, who finished bottom, and Ayr United in the play-offs. They were replaced by Second Division champions Cowdenbeath, and Dumbarton as winners of the promotion play-offs.

On 13 July, Rangers were admitted to the Third Division after being voted out of the SPL. As a result, the playoff losing finalist Airdrie United were promoted to the First Division to fill the gap caused by Dundee replacing Rangers in the SPL.
