2015 Longford Senior Football Championship

The 2015 Longford Senior Football Championship is the 99th running of the Longford GAA's premier club Gaelic football tournament for senior graded teams in County Longford, Ireland since the first County Championship was held in 1890 (98 completed since 1890, 1 started but not completed in 1891). The 2015 tournament consisted of 12 teams, with the winner going on to represent Longford in the Leinster Senior Club Football Championship. The championship starts with a league stage and then progresses to a knock out stage.

Killoe Young Emmets were the defending champions after they defeated Mullinalaghta St Columba's in the previous years final, and they successfully defended their title, defeating Abbeylara 1-14 to 1-11 on 4 October 2015 in Pearse Park.

This was Carrickedmond's return to the senior grade in 3 years since relegation in 2011 after claiming the 2014 Longford Intermediate Football Championship title, however they were due to make the drop straight back down to the Intermediate grade after losing a Relegation Playoff final before the format for the 2016 S.F.C. was changed.
