Carthage (Latin: Carthago or Karthago, Ancient Greek: Καρχηδών Karkhēdōn, Arabic: قرطاج Qarṭāj‎, Berber: ⴽⴰⵔⵜⴰⵊⴻⵏ Kartajen, Etruscan: *Carθaza, Modern Hebrew: קרתגו‎ Qartágo, from the Phoenician Qart-ḥadašt meaning New City (Aramaic: קרתא חדאתא, Qarta Ḥdatha), implying it was a 'new Tyre') is a major urban centre that has existed for nearly 3,000 years on the Gulf of Tunis, developing from a Phoenician colony of the 1st millennium BC. It is currently a suburb of Tunis, Tunisia, with a population of 20,715 (2004 Census).

The first civilization that developed within the city's sphere of influence is referred to as Punic (a form of the word "Phoenician") or Carthaginian. The city of Carthage is located on the eastern side of Lake Tunis across from the centre of Tunis. According to Greek historians it was founded by Phoenician colonists from Tyre under the leadership of Elissa who was re-named (Queen Dido) in Virgil's Aeneid. It became a large and rich city and thus a major power in the Mediterranean. The resulting rivalry with Syracuse and Rome was accompanied by several wars with respective invasions of each other's homeland.
