Tunis (Arabic:تونس‎  Tūnis) is both the capital and the largest city of Tunisia. The greater metropolitan area of Tunis, often referred to as Grand Tunis, holds some 2,700,000 inhabitants.

Situated on a large Mediterranean Sea gulf (the Gulf of Tunis), behind the Lake of Tunis and the port of La Goulette (Ḥalq il-Wād), the city extends along the coastal plain and the hills that surround it. At its core lies its antic medina, a world heritage site. Beyond this district lie the suburbs of Carthage, La Marsa, and Sidi Bou Said.
