The 1987 Cork Junior A Hurling Championship was the 90th staging of the Cork Junior A Hurling Championship since its establishment by the Cork County Board. The championship ran from 4 October to 1 November 1987.
The final was played on 1 November 1987 at Páirc Uí Chaoimh in Cork, between Cloyne and Ballincollig, in what was their first ever meeting in the final.[1] Cloyne won the match by 6-08 to 3-06 to claim their third championship title overall and a first title in 26 years.[2] Cloyne were not officially confirmed as champions until three weeks later when they won the delayed East Cork JAHC title.[3]
Cloyne's Ger Lewis was the championship's top scorer with 6-06.
