The 2017 Longford Senior Football Championship was the 101st 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 (100 completed since 1890, 1 started but not completed in 1891). The 2017 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 group stage and then progresses to a knock out stage.
Mullinalaghta St. Columba's were the defending champions after they defeated Abbeylara in the previous year's final. In the final, they repeated their victory over the same opponents, retaining their title for the first time ever.

Fr. Manning Gaels also joined them in the middle tier for the first time in 42 years, after losing their Relegation Play-off final.
