1972–73 Harty Cup

The 1972–73 Harty Cup was the 53rd staging of the Harty Cup since its establishment by the Munster Council of the Gaelic Athletic Association in 1918. The competition ran from 15 October 1972 to 11 March 1973.

St Finbarr's College were the defending champions. A change in format saw the winners of the B-grade Corn Phádraig enter at the semi-final stage.

The Harty Cup final was played on 11 March 1973 at Dr Mannix Sportsfield in Charleville, between St Finbarr's College and Cashel CBS, in what was their first ever meeting in the final. St Finbarr's College won the match by 5–14 to 2–05 to claim their fifth Harty Cup title overall and a third title in succession.

St Finbarr's College's Tadhg Murphy was the top scorer with 7-05.
