2017 Roscommon Senior Football Championship

The 2017 Roscommon Senior Football Championship is the 117th edition of Roscommon GAA's premier Gaelic football tournament for senior graded clubs in County Roscommon, Ireland. The tournament consists of 12 teams, with the winner representing Roscommon in the Connacht Senior Club Football Championship.

The championship starts with a seeded group stage and then progresses to a knock out stage.

St. Brigid's were the defending champions after they defeated Pádraig Pearse's in the previous years final, and they successfully defended their title to claim a "2-in-a-row" of championships and their 16th overall when defeating Roscommon Gaels 3-13 to 3-7 in the final at Dr. Hyde Park.

Kilmore bounced straight back to the top flight for this season from the Intermediate ranks after relegation in 2015, through claiming the 2016 I.F.C. title. However, they were relegated back to the middle tier for 2018 after losing the Relegation Final to Castlerea St. Kevin's.
