Société nationale maritime Corse-Méditerranée (SNCM) was a French ferry company operating in the Mediterranean.

Its ferries sailed from Marseille, Toulon, Nice on mainland France, Calvi, Bastia, Ajaccio, Ile Rousse, Propriano, and Porto Vecchio on Corsica, Porto Torres on Sardinia, Algiers, Oran, Skikda and Bejaia in Algeria as well as Tunis in Tunisia and Genoa in Italy.

In September 2005, French Prime minister Dominique de Villepin presented a project of privatization of the company.

In other words, the state-owned SNCM was to insure transport between the mainland and Corsica all year long, even though in exclusive market terms it may not be profitable, so that Corsicans can access administrative services as well as any other Frenchman.

Following hard negotiations and a strike by the CGT trade-union and the Corsican Workers' Trade Union (STC), a new project was presented.
