The art of "pizzaiulio" has apparently been handed down for centuries in Italy - was accepted for the world body's list of the Intangible Cultural Heritage of Humanity.
Almost two million people signed the petition to support Naples' application as they argued that the art of preparing and flipping the dough, topping it and then baking it in a wood-fired oven was a part of the country's cultural and gastronomic tradition.
In Rome, pizzeria owner Romano Fiore celebrated the decision. "I am honoured like all Italians and Neapolitans are...pizza has centuries of history," Fiore said.
"Victory!" Maurizio Martina, Italy's minister for agriculture, food and forestry, wrote on Twitter. "Another step towards the protection of Italy's food and wine heritage."
