The following is a summary of Donegal county football team's 2012 season. It was the franchise's 108th season since the County Board's foundation in 1905. The team ended the season as All-Ireland champions after winning Sam Maguire MMXII.
Jim McGuinness returned for his second season as the team's manager. Pioneer of the game's revolutionary tactic The System,[1] he entered the season having won the 2011 Ulster Senior Football Championship in his first season at the helm. Consecutive Ulster titles were a possibility, a first in team history, and the 2012 Ulster Senior Football Championship duly followed. McGuinness then became only the second manager, after Brian McEniff at the helm of the fabled Sam MCMXCII side, to lead Donegal to the All-Ireland title.
Conor McManus from Cork was part of the panel after transferring to Cill Chartha due to work commitments and being called into McGuinness's panel. He made his Donegal debut against UUJ at O'Donnell Park on 8 January, playing in midfield beside Neil Gallagher. He was half-time substitute against Cavan at Breffni Park on 15 January. His third and final appearance for the county came as a corner-forward against Derry at MacCumhaill Park on 18 January. McManus did not participate in Donegal's league campaign as by then his work brought him to Limerick, allowing him to return to his native club Clonakilty.[2]
L McLoone, F McGlynn 1-0 each, C McFadden (3f) 0-6 , Declan Walsh, R Bradley, M McHugh, M McElhinney 0-2 each, David Walsh, D McLaughlin, P McBrearty, M Murphy 0-1 each
Played under floodlights[3] at Casement Park in Belfast on Saturday 3 November 2012, this game was held in memory of Michaela McAreavey. Donegal, in their first outing as All-Ireland champions, played a team comprising players from the rest of Ulster in an event intended to raise funds for The Michaela Foundation.[4][5]

Devenney said [regarding the 2020 Donegal SFC final, ahead of its second postponement]: 'Kilcar are so well conditioned. They've Adam Speer in the background. He's a top man. He was with Donegal in 2012 and he knows how to get teams into that frame of physical fitness'.
