2013 Down Senior Football Championship
The 2013 Down Senior Football Championship was the 105th 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 a revamp of the competition format, which was approved at the end of the 2011 season, a group stage was introduced to the Championship for the first time. This format was only used for two seasons, and ran until the end of the 2014 competition.
Kilcoo were the holders after defeating Mayobridge in the 2012 final, and retained the title after defeating St Mary's Burren in the 2013 final.
