2018 Clare Senior Football Championship

The 2018 Clare Senior Football Championship will be the 123rd staging of the Clare Senior Football Championship since its establishment by the Clare County Board in 1887.

The defending champions and holders of the Jack Daly Cup were Kilmurry-Ibrickane who retained their crown to win their fifteenth overall senior title in October 2017.

In 2017 it was decided that from 2019 onwards the Clare Senior Football Championship would be cut from sixteen to twelve teams. This means that five clubs will lose their senior status and be relegated down to the Clare Intermediate Football Championship for 2019. The eleven remaining senior clubs will be joined by the 2018 intermediate champions to form the new championship.
