The 2015 Clare Senior Hurling Championship was the 120th staging of the Clare Senior Hurling Championship since its establishment by the Clare County Board in 1887.
The defending champions and holders of the Canon Hamilton Cup were Cratloe who won their second ever title. This formed part of a historic first Clare Senior Championship 'Double' since Ennis Dalcassians in 1929, which was completed when they defeated Éire Óg, Ennis in the football final the following weekend.
In 2012 it was decided that from 2014 onwards the heretofore separate Clare Senior A and Senior B Hurling Championships would be merged into a single sixteen-team senior hurling championship. This meant that five clubs would lose their senior status and be relegated down to the Clare Intermediate Championship. The fifteen remaining clubs would be joined by the 2013 intermediate champions to form the new single tier format. However, due to the success of the Clare Senior and Under-21 squads in 2013, the culling of the senior hurling championship was postponed for twelve months.
A mini Senior B championship will still be held for those clubs that avoid relegation but don't qualify for the quarter-finals.
