The 2015 Galway Senior Football Championship is the 120th edition of the Galway GAA's premier club Gaelic football tournament for senior graded teams in County Galway, Ireland. The tournament consists of 21 teams (N.U.I.G. only enter at the Preliminary Quarter-Final Stage), with the winner going on to represent Galway in the Connacht Senior Club Football Championship. The championship has a back-door format for the first two rounds before proceeding to a knock-out format. Generally, any team to lose two matches will be knocked out of the championship.
All-Ireland champions Corofin were the defending champions after they defeated St Michael's in the previous years final, and they successfully defended their title and also claimed a three-in-a-row of titles when beating Mountbellew-Moylough in the final at Tuam Stadium on 11 October 2015 by 3-13 to 0-12.
This was Killanin's first year back in the senior grade and they made it all the way to a Quarter-Final, losing narrowly to Salthill-Knocknacarra.
Kilkerrin-Clonberne were relegated to the Intermediate grade after 18 years in the top flight.
