The top four beaches on the list are found on the islands of Sicily, Sardinia and Ponza.
Five other Italian regions made it into the top 15, including Puglia, Campania, Le Marche, Abruzzo and Liguria.
However, the islands dominated the list, with three Sardinian beaches, three Sicilian beaches, and the lone Lazio beach on the island of Ponza.
The classification relied on tips from travellers and also took other criteria into account, including water clarity, beach cleanliness and the uniqueness of the surrounding the scenery.
The top beach honour went to Tonnarella dell'Uzzo, in the Zingaro nature reserve on Sicily - a seven-kilometre stretch of beach that runs from San Vito lo Capo to Castellammare del Golfo.
The island of Sardinia took second place with its Cala dei Gabbiani beach, which is still little-known because it is overshadowed by the fame of nearby Cala Mariolu beach.
In third place is the island of Ponza with its Cala Feola beach, located in the region of Lazio not far from Rome.
Sicily also took fourth place with the protected marine area known as Plemmirio, which was celebrated in the ancient world in the epic poem Aeneid written by Virgil between 29 and 19 BC. Nowadays, it's a top destination for scuba divers.
The third Sicilian beach in the top 15, at number six, is Capo Graziano on the island of Filicudi, one of the eight Aeolian Islands just northeast of Sicily, which are part of Sicily's province of Messina.
Campania took the fifth place spot, with its Marina Grande beach in Positano, a town perched high on a cliff along the Amalfi Coast.
The two other Sardinian beaches on the list are Cala Cipolla in eighth place with its white sands, and Cala Luna, made famous in the 1974 Lina Wertmuller film ‘Swept Away’, ranking number 14.
Puglia took the seventh and 10th places with Torre di Sant'Andrea and Baia di Punta Rossa, respectively.
