The Kilkenny Premier Junior Hurling Championship (known for sponsorship reasons as the JJ Kavanagh & Sons Premier Junior Hurling Championship and abbreviated to the Kilkenny PJHC) is an annual hurling competition organised by the Kilkenny County Board of the Gaelic Athletic Association and contested by the top-ranking junior clubs in the county of Kilkenny in Ireland. It is the third tier overall in the entire Kilkenny hurling championship system.
Introduced in 1905 as the Kilkenny Junior Hurling Championship for teams deemed not eligible for the senior grade or second-string senior teams, it eventually became a divisional competition with the North and South champions playing each other for the county title. At the time of its creation it was the second tier of Kilkenny hurling. The competition took on its current name in 2022, when the entire junior hurling championship system was reformed.
In its current format, the Kilkenny Premier Junior Championship is played across the autumn months. The participating teams are split into Section A and Section B and engage in a knockout competition that culminates with the final at UPMC Nowlan Park.
Mooncoin is the most successful team in the tournament's history, having won it seven times. St Lachtain's are the current champions after beating Windgap in the 2024 final.
