Giacinto Bonaventura Longhin - in religious Andrea di Campodarsego - was an Italian Roman Catholic prelate and professed member from the Order of Friars Minor Capuchin who served as the Bishop of Treviso from 1904 until his death. Longhin held various roles of leadership within his order following his ordination such as acting as a teacher in Udine and acting as the Provincial Minister for his order. He became close friends with Giuseppe Melchiorre Sarto, Cardinal Patriarch of Venice. The latter became Pope Pius X in 1903 who made his old friend Longhin the new head for the vacant Treviso episcopal see.
