Alessandro Damasceni Peretti di Montalto (1571 - 1623) was an Italian Roman Catholic Cardinal Deacon. He received the title by his uncle Felice Peretti after the latter was elected Pope Sixtus V on April 24, 1585, in the consistory on May 13; the cardinal was then fourteen years old. The Republic of Venice inscribed him in the Libro d'Oro as a patrician of Venice that same year. Though he was made the permanent governor of Fermo the following year, and was often the papal legate in Bologna, he was not made a bishop until 1620, when he became Cardinal-Bishop of Albano. He served also as Vice-Chancellor of the Holy Roman Church (1589-1623) and Cardinal Protector of the Kingdom of Poland (named on September 30, 1589 by King Zygmunt III Waza) and of the several religious orders.
