The 2018 Carlow Senior Football Championship is the 118th edition of the Carlow GAA's premier club gaelic football tournament for senior graded clubs in County Carlow, Ireland. The tournament consists of 8 teams, with the winner going on to represent Carlow in the Leinster Senior Club Football Championship. The championship starts with a group stage and then progresses to a knock out stage.
Éire Óg were the defending champions after they defeated Rathvilly in the previous years final.
This was the Kilbride's return to the senior grade after claiming the 2017 Carlow Intermediate Football Championship title, thus ending a 3-year exodus since being relegated in 2014. However, they were relegated straight back to the 2019 I.F.C. after losing their Relegation Playoff Final at the hands of Old Leighlin.
The following teams have changed division since the 2017 championship season.
Promoted from 2017 Carlow Intermediate Football Championship
