Nazario is an Italian given name, derived from the Latin word "Nazarus," which means "of Nazarus" or "from Nazareth." It is believed to have been popularized during the Middle Ages through the veneration of Saint Nazarius, one of the Four Crowned Martyrs in Christian tradition. The name has since become more widespread, particularly in Italy and among Italian communities around the world.
The name Nazario saw a significant rise in popularity from the late 1970s onwards, with over 15 births recorded annually since 1986. The peak occurred recently, with 31 births in 2021 and 30 births in 2023.
