Carthage (/ˈkɑːrθɪdʒ/ KAR-thij; Arabic: قرطاج, romanized: Qarṭāj) is a commune in Tunis Governorate, Tunisia. It is named for, and includes in its area, the archaeological site of Carthage.

Established in 1919, Carthage is some 15 km to the east-northeast of Tunis, situated between the towns of Sidi Bou Said to the north and Le Kram to the south. It is reached from Tunis by the R23 road via La Goulette, or by the N9 road via Tunis–Carthage International Airport.

The population as of January 2013 was estimated at 21,277, mostly attracting the more wealthy residents. The Carthage Palace (the Tunisian presidential palace) is located on the coast.

Carthage has six train stations of the TGM line between Le Kram and Sidi Bou Said: Carthage Salammbo (named for the ancient children's cemetery where it stands), Carthage Byrsa (named for Byrsa hill), Carthage Dermech (Dermèche), Carthage Hannibal (named for Hannibal), Carthage Présidence (named for the Presidential Palace) and Carthage Amilcar (named for Hamilcar).

Roman Carthage was destroyed following the Muslim invasion of 698, and it remained under the control of the Arabs and later Ottoman rule for more than a thousand years (being replaced in the function of regional capital by the Medina of Tunis), until the establishment of the French protectorate of Tunisia in 1881.

The cathedral of St. Louis of Carthage was built on Byrsa hill in 1884. In 1885, Pope Leo XIII acknowledged the revived Archdiocese of Carthage as the primatial see of Africa and Charles Lavigerie as primate. European-style villas were built along the beach beginning in 1906; one such villa was chosen by Habib Bourguiba as the presidential palace in 1960.

The municipality was created by a decree of the Bey of Tunis on 15 June 1919, during the rule of Naceur Bey.

Construction on the Tunis–Carthage International Airport, which was fully funded by France, began in 1944, and in 1948 the airport become the main hub for Tunisair.
