The 2011–12 Scottish Football League First Division, also known as the 2011–12 Irn Bru Scottish Football League First Division for sponsorship reasons, is the 18th season of the Scottish First Division and the 106th season of a second-tier football league in Scotland. Dunfermline Athletic are the current champions. It began on 6 August 2011 and is scheduled to end on 5 May 2012. The league comprises the teams ranked second through eighth of the 2010–11 season, the relegated side from the 2010–11 Premier League (Hamilton Academical), the 2010–11 Second Division champions, and the winners of the 2010–11 First Division play-off (Livingston and Ayr United respectively).
Dunfermline Athletic, champions of the 2010–11 season, were promoted to the 2011–12 Premier League.[3] The club thus completed a five-season tenure in the First Division. Dunfermline were replaced by Hamilton Academical, who were relegated from the 2010–11 Premier League after finishing at the bottom of the table;[3] Hamilton returned to the First Division after three years.
At the bottom end of the table, last-placed Stirling Albion were directly relegated to the 2011–12 Second Division[3] after being promoted to the second tier only one season earlier. They were replaced by the 2010–11 Second Division champions Livingston,[3] who returned to the First Division after two consecutive promotions in two years; the club had previously been demoted for financial irregularities at the end of the 2008–09 season.[4]
An additional place in the league was available via a play-off tournament between the ninth-placed First Division team, Cowdenbeath, and the sides ranked second through to fourth in the Second Division, Ayr United, Forfar Athletic and Brechin City respectively. The tournament was won by Ayr United,[3] who therefore were promoted back to the First Division after a one-year absence; Cowdenbeath hence were relegated,[3] returning to the Second Division after just one season.
Teams play each other four times in this league. In the first half of the season each team plays every other team twice (home and away) and then do the same in the second half of the season, for a total of 36 games
