Saint Silvestro Guzzolini (†1267) was an Italian Catholic priest and the founder of the Silvestrine Order. He served as a canon in Osimo but respectful rebukes of his bishop's inappropriate conduct led him to leave for a hermitage before the bishop could strip him of his position. He remained in his hermitage with a determination to found a religious congregation and based it upon the Order of Saint Benedict after having a dream of Benedict of Nursia. His order received papal approval from Pope Innocent IV which allowed his order to expand across Italian cities to a significant degree. His beatification was confirmed in the 1260s after his death in 1267, and he was later canonized in 1598 as a saint.
