The Diocese of Lesina (Latin: Dioecesis Lesinensis) was a Roman Catholic diocese located in the town of Lesina on the northern side of Monte Gargano in the province of Foggia, in the Apulia region of southeast Italy. Erected in the 13th century, it was suppressed in 1567 to the Diocese of Larino.[1][2] It was restored as a titular see in 1968.[2][3]
