The 1966 All-Ireland Junior Hurling Championship was the 45th staging of the All-Ireland Junior Championship since its establishment by the Gaelic Athletic Association in 1912.[1] [2]
Roscommon entered the championship as the defending champions, however, they were beaten in the Ulster Championship.[3] [4]
The All-Ireland final was played on 9 October 1966 at Glebe Farm, between Kildare and Warwickshire, in what was their first ever meeting in the final. Kildare won the match by 4-06 to 2-09 to claim their second championship title overall and a first title in four years.[5]
