The Compagnie Tunisienne de Navigation (CTN or COTUNAV) is a Tunisian shipping line, providing regular passenger ferry connections between Tunisia and the ports of Marseille and Genoa, as well as freight transport to Barcelona and Livorno.

Founded on 7 March 1959, it initially concentrated on the development of regular shipping links between Tunisia and its principal trading partners, essentially serving only Marseille and Rouen.

However, with the drive to diversify Tunisian overseas trade, it rapidly expanded its route network to encompass ports in Italy, Spain, Germany and the Benelux countries.

With the commissioning in 1978 of the ferry Habib, providing service between Tunis, Marseille and Genoa, it also increased its involvement in passenger transport.
