Tirrenia is a privately-owned Italian shipping company contracted by the Ministry of Transportation to run ferry services between Italy's mainland and its major islands.

[2] After World War II, the few ships surviving the conflict were used to connect Italian islands, mainly Sardinia, to the mainland.

[2] Since the end of the 1980s, the company replaced its older units, most of which were obsolete or too expensive to operate and were then scrapped, with faster ones capable of reaching 35–40 knots.

On 23 December 2009, the Italian government, after having subsidised the company for some years, put Tirrenia on the market through its privatisation agency Fintecna.

In 2014, the company moved from its historic Naples headquarters of Rione Sirignano to Calata Porta di Massa, Interno Porto.
