Saint Joseph Marello (December 26, 1844 - May 30, 1895) was the son of Vincenzo and Anna Maria Marello. Joseph's mother died when he was very young, and the family moved from Turin to San Martino Alfieri, Italy.

Joseph entered the seminary at age 12. At age 19 he contracted typhus and promised Our Lady that if he survived, he would continue his studies to be ordained. He recovered, attributed the cure to Our Lady of Consolation, and was ordained on 19 September 1868.

Joseph became the secretary to Bishop Carlo Savio at Asti, Italy for 13 years. He attended the First Vatican Council with Bishop Savio in 1869-1870. Later, he took over an Asti retirement home to save it from bankruptcy. Joseph became the spiritual director and catechist in his diocese. In 1878, Joseph became the founder of the Oblates of Saint Joseph, a congregation dedicated to caring for the poor, educating the young, and assisting bishops in any capacity required. On February 17, 1889, he became the Bishop of Acqui, Italy. Joseph visited all the parishes in his diocese, and wrote six pastoral letters to his flock. He died while participating in a celebration of the 3rd centennial of St. Philip Neri.
