The Cork Junior A Hurling Championship (known for sponsorship reasons as the Co-Op Superstores Cork Junior A Hurling Championship and abbreviated to the Cork JAHC) is an annual hurling competition organised by the Cork County Board of the Gaelic Athletic Association and contested by the top-ranking junior clubs in the county of Cork in Ireland. It is the sixth tier overall in the entire Cork hurling championship system and is regarded as one of the toughest club competitions to win. The Cork Junior Championship was introduced in 1895 as a countywide competition for teams deemed not eligible for the senior grade or second-string senior teams. At the time of its creation it was the second tier of Cork hurling. In its current format, the Cork Junior A Championship begins in September following the completion of the seven Divisional Junior Championships. The 7 participating teams compete in a single-elimination tournament which culminates with the final match at Páirc Uí Rinn in October or November. The winner of the Cork Junior A Championship, as well as being presented with the John Quirke Cup, gains promotion to the Cork Premier Junior Hurling Championship. The competition has been won by 72 teams, 28 of which have won it more than once. Carrigtwohill are the most successful team in the championships history, having won it 6 times. Erin's Own are the title holders, beating Kilshannig by 1-30 to 3-20 after extra time after a replay in the 2022 final. (en)
