Bad Ischl is a spa town in Austria. It lies in the southern part of Upper Austria, at the river Traun in the centre of the Salzkammergut region. The town consists of the Katastralgemeinden Ahorn, Bad Ischl, Haiden, Jainzen, Kaltenbach, Lauffen, Lindau, Pfandl, Perneck, Reiterndorf and Rettenbach. It is connected to the village of Strobl by the river Ischl, which drains from the Wolfgangsee, and to the Traunsee, into which the stream empties. It is home to the Kaiservilla, summer residence of Austro-Hungarian monarchs Emperor Franz Joseph I and Empress Elisabeth. In 2024, Bad Ischl will be one of the European Capitals of Culture – the third city in Austria after Graz (2003) and Linz (2009).

The Salzkammergut is a resort area in Austria, stretching from the city of Salzburg eastwards along the Alpine Foreland and the Northern Limestone Alps to the peaks of the Dachstein Mountains. The main river of the region is the Traun, a right tributary of the Danube.
