2022 Donegal Senior Football Championship

The 2022 Donegal Senior Football Championship was the 100th official edition of Donegal GAA's premier Gaelic football tournament for senior graded clubs in County Donegal. 16 teams competed, with the winner representing Donegal in the Ulster Senior Club Football Championship.

St Eunan's was defending champion after defeating Naomh Conaill in the 2021 final.

Naomh Conaill advanced again, to the 2022 final, where the club won this time, but in controversial circumstances, and by one point, after St Eunan's player Shane O'Donnell was sent off for patting Jeaic Mac Ceallabhuí.

St Eunan's had a 16-point (2–15 to 0–5) win against St Michael's at Davy Brennan Memorial Park.

The other two quarter-finals saw Gaoth Dobhair emerge with a one-point (0–8 to 0–7) win against Aodh Ruadh at Fintra, while Naomh Conaill defeated Glenswilly by 2–10 to 0–10 at O'Donnell Park.

Semi-finals
A draw was held to determine the semi-final pairings.

The first semi-final — between Cill Chartha and St Eunan's — was scheduled for 20:00 on Saturday 24 September at MacCumhaill Park, and to be streamed live (pay-per-view) on Donegal GAA TV, while the second semi-final — between Gaoth Dobhair and Naomh Conaill — was scheduled for 16:00 on Sunday 25 September also at MacCumhaill Park, and also to be streamed live (pay-per-view) on Donegal GAA TV. However, the first semi-final was postponed until the following weekend, due to bereavements (the father and sister of Brendan Devenney had both died, suddenly, and separately).

Naomh Conaill defeated Gaoth Dobhair by 0–13 to 1–8 in what was to have been the second semi-final, but ended up being the first played. St Eunan's defeated Cill Chartha by 1–13 to 1–11 in the other semi-final, with both victors qualifying for the 2022 championship final.

Final
This was Naomh Conaill's sixth consecutive appearance in the final. The club won a sixth title.

Originally scheduled for 9 October 2022, the game was called off in the aftermath of the Creeslough explosion.

A minute's silence was held before the game. Black armbands were also worn.

Naomh Conaill won this one, but in controversial circumstances, and by one point, after St Eunan's player Shane O'Donnell was sent off for patting Jeaic Mac Ceallabhuí.

Ulster Senior Club Football Championship
Naomh Conaill advanced to the 2022 Ulster Senior Club Football Championship.

The club lost its quarter-final, on penalties.

Relegation play-offs
Four teams qualified for the 2022 Donegal SFC relegation play-offs.

Both semi-finals were held on Sunday 25 September. Ard an Rátha v St Naul's was played at Eamonn O'Broinn Memorial Park from 13:00, and streamed live (pay-per-view) on Donegal GAA TV; Milford v Réalt na Mara was played at Páirc Aodh Rua from 13:30, and streamed live (and available for free) on Donegal Facebook.

The two losing semi-finalists were St Naul's (defeated by 3–6 to 0–9) and Réalt na Mara (defeated by 4–16 to 3–16, after extra time).

St Naul's — achieving a first win in the 2022 SFC — defeated Réalt na Mara by 0–13 to 1–6 in the play-off final at Tírconaill Park, thus relegating Réalt na Mara to the 2023 Intermediate Championship.
