The 2009–10 Scottish Football League Third Division (also known as the 2009–10 Irn-Bru Scottish Football League Third Division for sponsorship reasons) was the 16th season in the format of ten teams in the fourth-tier of Scottish football. The season started on 8 August 2009 and ended on 1 May 2010. Livingston F.C. finished top and were promoted alongside Forfar Athletic as play-off winners.
A second promotion place was available via a play-off tournament between the ninth-placed team of the 2008–09 Scottish Second Division, Queen's Park, and the sides ranked second, third and fourth in the 2008–09 Scottish Third Division, Cowdenbeath, East Stirlingshire and Stenhousemuir respectively. The play off was won by Stenhousemuir who defeated Cowdenbeath in the final. Queen's Park were therefore relegated. However, Livingston F.C. were demoted to the Third Division, leading to an extra promotion being awarded.[1] Cowdenbeath as runners-up of the play-off final were therefore promoted.
