2015 Down Senior Football Championship

The 2015 Down Senior Football Championship was the 107th 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.

Following the conclusion of the 2014 competition, the group stage format was removed. In its place, the 2015 tournament used 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.

Kilcoo were the holders after defeating St Mary's Burren in the 2014 final, and retained the title after defeating Castlewellan in the 2015 final.

Round 1
The 16 participating teams were placed into an open draw. Winning sides move to Round 2A while losing sides go into Round 2B.

Round 2A
Round 2A will feature the eight winning sides from Round 1, with an open draw to determine the fixtures. The winning sides progress directly to the Quarter Final, with the losing sides moving into Round 3.

Round 2B
Round 2B sees the eight losing sides from Round 1 compete for a place in Round 3. The losing sides from this round will be eliminated from the competition.

Round 3
Round 3 is a supplementary round for teams to have a second chance at reaching the Quarter Final. This round features teams that have lost once so far in this year's Championship, either winning in Round 1 and losing in Round 2A, or losing in Round 1 but winning their Round 2B fixture. Losing sides in this round are eliminated from this year's competition.

This round is seeded, meaning in each fixture a Round 2A losing side will face a Round 2B winning side.

Quarter Final
The Quarter Final sees the two brackets rejoin, with the earlier Round 2A winners facing a Round 3 winner for a Semi Final spot.

Semi Final
The Semi Final will see the four winning sides face off for a place in this year's final. This round is an open draw from the four Quarter Final winners.

Final
The final will be played between the two Semi Final winners, and will take place at Páirc Esler, Newry.
