2019 Donegal Senior Football Championship
The 2019 Donegal Senior Football Championship was the 97th official edition of Donegal GAA's premier Gaelic football tournament for senior graded clubs in County Donegal. 16 teams compete with the winner representing Donegal in the Ulster Senior Club Football Championship. The championship begins with four groups of four and continues with a knock-out format.

Gaoth Dobhair were the defending Donegal and Ulster champions after they defeated Naomh Conaill of Glenties 0-17 to 1-7 in the 2018 final. However they failed to defend their crown, losing the final to Naomh Conaill by one point after a second replay. 

This was Glenfin's return to the senior grade after a two-year exodus when claiming the 2018 I.F.C. title.

Malin were relegated back to the 2020 I.F.C. after 16 seasons in the top-flight when losing their Relegation Final to Ardara. Back in 2003, Malin gained promotion to the S.F.C. for the first time in the club's history. Although Malin lost the I.F.C. Quarter-Final to eventual champions St. Michael's that year, they earned promotion to Division 1 from Division 2 of the Donegal Leagues. At that time, promotion to the S.F.C. could be acquired through the leagues.
