The Cork Junior B Hurling Championship (known for sponsorship reasons as the Co-Op Superstores Cork Junior B Hurling Championship and abbreviated to the Cork JBHC) is an annual hurling competition organised by the Cork County Board of the Gaelic Athletic Association and contested by the second tier junior clubs in the county of Cork in Ireland. It is the seventh tier overall in the entire Cork hurling championship system. The Cork Junior B Championship was introduced in 1984 as a countywide competition for "weaker" junior teams. At the time of its creation it was the fourth tier of Cork hurling. The Cork Junior B Championship is unlike all other championships in Cork in that it doesn't include a group stage. In its current format, the teams compete in a double-elimination tournament which culminates with a final. The winner of the Cork Junior B Championship qualifies for the subsequent Munster Club Championship. The competition has been won by 30 teams, 6 of which have won it more than once. Ballyhooly, Castletownroche, Harbour Rovers, Lisgoold, O'Donovan Rossa and Randal Óg are the most successful teams in the tournament's history, having won it 2 times each. Freemount are the reigning champions after beating Randal Óg by 1-18 to 1-17 in the 2022 final. In 2015, a second Junior B Championship (known as Inter-Divisional Championship) was introduced to run parallel with the traditional Junior B Championship. Mirroring the Junior A Hurling Championship, this competition allows all the Junior B divisional champions an opportunity to win a county. Unlike the traditional Championship, second string teams can enter the divisional championships and potentially win the county championship. 2023 Teams County Championship (8) Interdivisional Championship (7) Formats County Championship Round 1: All teams contest this round.
