The launch of the new editions means that Metro in Italy now has a print-run of 850,000 copies each day, making it the highest-circulation daily newspaper.
Pelle Tornberg, the president and chief executive of Metro, said: "Our expansion in Italy reflects the success of Metro Italy as well as the demand from our advertising clients for national coverage.
"Today, Metro becomes the leading-nationally distributed daily newspaper in Italy and the expansion will provide Metro with additional advertising revenue streams."
Metro now publishes 52 daily Metro editions around the world in 17 different countries. This includes the Metro in New York and Paris.
