The 2019 Down Senior Football Championship was the 111th official edition of Down GAA's premier Gaelic Football tournament for senior clubs in County Down. 16 teams competed with the winner representing Down in the Ulster Senior Club Football Championship. The tournament operated a double elimination format for the opening two rounds of the championship, with the winners and early round losers rejoining at the quarter-final stage.
Bredagh made their return to the senior grade after claiming the Down I.F.C. title in 2018.
St. Mary's Burren were the holders after they ended Kilcoo's run of six titles in a row, defeating the then defending champions on a scoreline of 2-12 to 2-09 in the 2018 final.[1] They were unable to defend their title however, as they were eliminated in the quarter-final, losing to last year's finalists Kilcoo after a replay.[2][3]
An Ríocht and Saval were relegated to the 2020 I.F.C. after finishing outside the top 15 ranked teams in the Down football leagues for 2018. They finished 5th and 8th (ranked 16th and 19th overall) in Division 2 respectively. Glenn John Martin's and Darragh Cross will replace them after they claimed the 2019 I.F.C. title and finished 4th (ranked 15th overall) in Division 2 respectively.
