The Carbery Junior A Hurling Championship (known for sponsorship reasons as the RCM Tarmacadam Carbery Junior A Hurling Championship) is an annual club hurling competition organised by the West Cork Board of the Gaelic Athletic Association and contested by the top-ranking junior clubs in West Cork, Ireland, deciding the competition winners through a group stage and knockout format. It is the most prestigious competition in West Cork hurling.
Introduced in 1925 as the West Cork Junior Championship, it was initially a straight knockout tournament. The competition went through a number of format changes since then, including the introduction of a back-door or second chance for beaten teams. The competition took on its current format in 2022, adding a round-robin group stage and limiting the number of entrants.
In its current format, the Carbery Junior Championship begins with a group stage in late summer. The 12 participating teams are divided into three groups of four and play each other in a round-robin system. The two top-ranking teams in each group proceed to the knockout phase that culminates with the final. The winner of the Carbery Junior Championship, as well as receiving the Flyer Nyhan Cup, also qualifies for the subsequent Cork Junior A Hurling Championship.
The competition has been won by 13 teams, 12 of which have won it more than once. Clonakilty are the most successful team in the tournament's history, having won it 18 times. Diarmuid Ó Mathúna's are the title holders, defeating Ballinascarthy by 1–14 to 1–12 on 3 November 2024.
