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.
