A number of Italian Cheeses have Protected Designation of Origins (PDO) status under European Union regulations. This protection enables only Italian Cheese producers from particular regions to sell and promote the cheeses listed below. Prior to PDO, many Italian cheeses were protected under an Italian regulation called Denominazione di Origine before being superseded.
