Hallstatt is a small town in the district of Gmunden, in the Austrian state of Upper Austria.
Situated between the southwestern shore of Hallstätter See and the steep slopes of the Dachstein massif, the town lies in the Salzkammergut region, on the national road linking Salzburg and Graz.
Hallstatt is known for its production of salt, dating back to prehistoric times, and gave its name to the Hallstatt culture, the archaeological culture linked to Proto-Celtic and early Celtic people of the Early Iron Age in Europe, c. 800–450 BC.
Hallstatt is at the core of the "Hallstatt-Dachstein/Salzkammergut Cultural Landscape" declared as one of the World Heritage Sites in Austria by UNESCO in 1997. It is an area of overtourism.
