John Mary Harty (11 August 1867 – 11 September 1946) served as Roman Catholic Archbishop of Cashel from 1913 until his death in 1946. He served as Patron of the Gaelic Athletic Association from 1928. The Dr. Harty Cup, the trophy for Munster Schools Hurling, is named in his honour, as is the playing field of his native Murroe GAA club.
