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 competed, with the winner representing Donegal in the Ulster Senior Club Football Championship. The championship began with four groups of four, and continued with a knock-out format.
The defending Donegal (and Ulster) champion was Gaoth Dobhair, after the club defeated Naomh Conaill by a scoreline of 0–17 to 1–7 in the 2018 final. However, Gaoth Dobhair failed to defend its 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 suffered relegated back to the 2020 I.F.C. after 16 seasons in the top-flight, when losing its relegation final. 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 champion St Michael's that year, the club 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.
The following teams changed division since the 2018 championship season.
Promoted from 2018 Donegal I.F.C.
Relegated to 2019 Donegal I.F.C.
The 2019 County Championship took the same format as previous championships in which there was four groups of four with the top two qualifying for the quarter-finals. Bottom of each group play in relegation play-offs to decide which team is relegated the 2020 Intermediate championship.
All 16 teams enter the competition at this stage. The top 2 teams in each group go into the Quarter-Finals while the bottom team of each group entered a Relegation Playoff.
