The 1977 All-Ireland Junior Hurling Championship was the 56th staging of the All-Ireland Junior Championship since its establishment by the Gaelic Athletic Association in 1912. Louth began the competition as defending champions, having defeated Mayo in the 1976 decider.[1] Louth beat Fermanagh in the 1977 final to retain their title.
Provincial hurling championships were not held at junior level in 1977. The winners of the respective 'A' and 'B' sections of the National Hurling League Division 3 would go forward to contest the All-Ireland final.
Louth reached their third consecutive final after a League campaign which included victories against Derry (twice), Monaghan and Tyrone.[2] Fermanagh's path to the final included wins against Donegal, Sligo, Leitrim, and Mayo.[3]
Louth led by seven points at half-time (1-08 to 1-01) and at the final whistle emerged as winners by a ten-point margin.[4] [5]
