The Kilkenny county hurling team represents Kilkenny in hurling and is governed by Kilkenny GAA, the county board of the Gaelic Athletic Association. The team competes in the three major annual inter-county competitions; the All-Ireland Senior Hurling Championship, the Leinster Senior Hurling Championship, and the National Hurling League. Historically, Kilkenny is the most successful team at senior level.

The GAA Hurling All-Ireland Senior Championship, known simply as the All-Ireland Championship, is an annual inter-county hurling competition organised by the Gaelic Athletic Association (GAA). It is the highest-tier competition for inter-county hurling in Ireland and has been contested in every year except one since 1887.
