Antonio Maria Gianelli was an Italian Roman Catholic bishop who lived from 1789 to 1846. Born in Carro, he pursued his studies in Genoa before being ordained as a priest in 1812. He later served as the Bishop of Bobbio, a position he held from 1837 until his death in Piacenza. Throughout his religious life, he established two significant congregations, the Missionaries of Saint Alphonsus and the Figlie di Nostra Signora del Giardino.
