The Mid Cork Junior A Football Championship (known for sponsorship reasons as the Ross Oil Junior A Football Championship) is an annual club Gaelic football competition organised by the Mid Cork Board of the Gaelic Athletic Association and contested by junior-ranked teams in the Muskerry region in County Cork, Ireland, deciding the competition winners through a group and knockout format.
Introduced in 1926 as the Mid Cork Junior Football 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.
In its present format, the 12 teams are drawn into three groups of four teams and play each other in a single round-robin system. The four group winners and four group runners-up proceed to the knockout phase that culminates with the final. The winner of the Mid Cork Junior A Championship, as well as being presented with the cup, qualifies for the subsequent Cork Junior A Football Championship.
The title has been won at least once by 18 different clubs. The all-time record-holders are Canovee, who have won a total of 17 titles. Canovee are the title-holders after defeating Inniscarra by 1-15 to 2-06 in the 2023 final.
