Giuseppe Marello was an Italian Roman Catholic prelate who served as the Bishop of Acqui from 1889 until his death and was also the founder of the Oblates of Saint Joseph. Marello served as an aide to the Bishop of Asti prior to his episcopal appointment after Pope Leo XIII named him to head the Acqui diocese; the pope had known Marello while a cardinal when the pair participated in the First Vatican Council more than a decade before. He became a proponent for the poor and destitute and never stopped rendering his assistance to those who needed it the most; this was something he undertook even in his childhood. Bishop Marello issued several pastoral letters that dealt with a range of issues such as catechism and organized one big pastoral visitation to visit all parishes in his diocese.
