The 1981 Cork Senior Hurling Championship was the 93rd staging of the Cork Senior Hurling Championship since its establishment by the Cork County Board in 1887. The championship began on 10 May 1981 and ended on 13 September 1981.
St. Finbarr's entered the championship as the defending champions.
The final was played on 13 September 1981 at Páirc UàChaoimh in Cork, between St. Finbarr's and Glen Rovers, in what was their second successive meeting in the final. St. Finbarr's won the match by 1âÂÂ12 to 1âÂÂ09 to claim their 21st championship title overall and a second successive title.
Christy Ryan was the championship's top scorer with 6-05.
At the County Convention on 25 January 1981, it was decided to end the three-year experiment of playing the championship on a league basis in the preliminary rounds and reverted to an open, seeded draw. The four semi-finalists from the 1980 championship (Midleton, Blackrock, St. Finbarr's and Glen Rovers) were the four seeded teams and were separated in the quarter-final stage.
