Alessandro Damasceni Peretti di Montalto was an Italian Catholic Cardinal Bishop. He received the title from his great-uncle Felice Piergentile after the latter was elected Pope Sixtus V on 24 April 1585, in the consistory on 13 May, and was installed as Cardinal Deacon of San Girolamo dei Croati on 14 June 1585; 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 and of the several religious orders.
