Dougga or Thugga (Berber: Dugga, Tugga, Tunisian Arabic:دڨة‎  Doggā) is an ancient Roman city in northern Tunisia, included in a 65 hectare archaeological site.

UNESCO qualified Dougga as a World Heritage Site in 1997, believing that it represents “the best-preserved Roman small town in North Africa”. The site, which lies in the middle of the countryside, has been protected from the encroachment of modern urbanisation, in contrast, for example, to Carthage, which has been pillaged and rebuilt on numerous occasions.
