The Duhallow Junior A Hurling Championship (known for sponsorship reasons as the Kanturk Co-Op Mart Junior A Hurling Championship) is an annual hurling competition organised by the Duhallow Board of the Gaelic Athletic Association since 1933 for junior hurling teams in the Barony of Duhallow in County Cork, Ireland. The series of games are played during the summer and autumn months. The championship starts with 2 groups and the group winners and runners-up advance to the knockout stage. This gives each team at least 3 matches. The Duhallow Junior A Hurling Championship is an integral part of the wider Cork Junior A Hurling Championship. The winners of the Duhallow championship join their counterparts from the other six divisions to contest the county championship. Dromtarriffe are the title-holders, defeating Newmarket by 3–18 to 3–14 in the 2024 final.

Format

Group stage

The 8 teams are divided into two groups of four. Over the course of the group stage, each team plays once against the others in the group, resulting in each team being guaranteed at least three games. Two points are awarded for a win, one for a draw and zero for a loss. The teams are ranked in the group stage table by points gained, then scoring difference and then their head-to-head record. The top two teams in each group qualify for the knockout stage.

Knockout stage

Semi-finals: The two group winners and the two runners-up from the group stage contest this round. The two winners from these games advance to the final. Final: The two semi-final winners contest the final. The winning team are declared champions.

Promotion and relegation

At the end of the championship, the winning team enters the Cork Junior A Hurling Championship and by winning this, they will be promoted to the Cork Premier Junior Hurling Championship for the following season. There is no relegation to the Duhallow Junior B Hurling Championship.
