The Basilica of Saint Joseph Proto-Cathedral is a Catholic parish church at 310 West Stephen Foster Avenue in Bardstown, Kentucky. It is the original cathedral of the present Roman Catholic Archdiocese of Louisville, originally erected as the Diocese of Bardstown — "proto-cathedral" means the former cathedral of a see that has transferred or moved. During its years as a cathedral, the pastor was Benedict Joseph Flaget, the first bishop of Bardstown.
