Waldshut-Tiengen (German pronunciation: [ˈvaltshuːt ˈtiːŋən]; Alemannic: Waldshuet-Düenge), commonly known as Waldshut, is a city in southwestern Baden-Württemberg right at the Swiss border.

There are furthermore complexities arising from cross-border traffic between this area and the Swiss cantons of Aargau, Schaffhausen and Zürich.

This classification relates to Walter Christaller's Central Place Theory, however, and not to any official administrative scheme.

The city, which was newly created in the framework of the 1975 municipal reform, at that time passed the 20,000 mark in population.

Waldshut-Tiengen lies at the edge of the southern Black Forest, right on the Rhine river, along which runs the German-Swiss border.

The Waldshut townsite lies about 2 km west of where the river Aar empties into the Rhine.

The list runs clockwise, starting in the west: Dogern, Albbruck, Dachsberg, Weilheim, Ühlingen-Birkendorf, Wutöschingen, Lauchringen and Küssaberg (all in Waldshut district) and furthermore, across the Rhine, Koblenz, Leuggern and Full-Reuenthal (all in the canton of Aargau).

These are Aichen (with Gutenburg), Breitenfeld, Detzeln, Eschbach, Gurtweil, Indlekofen, Krenkingen, Oberalpfen and Waldkirch (with Gaiß and Schmitzingen).

This means that they each have a community council chosen by the eligible voters at each municipal election, and each one with a chairperson.

Tiengen/Hochrhein (until 2 September 1964 Tiengen (Oberrhein)) was the residence of the Landgraves of Klettgau who belonged in early modern times first to the Counts of Sulz, and after their line died out, to the Fürsten of Schwarzenberg.

As a result of belonging to Further Austria, Waldshut and its environs remained overwhelmingly Catholic until the 19th century.

The neighbouring town of Tiengen and its environs also remained overwhelmingly Catholic, albeit with a few of Hubmaier's followers who believed in his Anabaptist teachings.

As of 1821, the Catholic communities in today's Waldshut-Tiengen belonged to the Archbishopric of Freiburg, and indeed to the two deaconries of Waldshut and Wutachtal.

The pastoral unit of Maria Bronnen includes the parishes of St. Marien Waldkirch, St. Sebastian Aichen and St. Simon und Judas Gurtweil as well as the neighbouring parishes of St. Peter und Paul Weilheim, St. Stephan Weilheim-Nöggenschwiel, St. Pankratius Berau and St. Laurentius Brenden (both in the community of Ühlingen-Birkendorf).

The pastoral unit of Waldshut includes the Liebfrauengemeinde and the neighbouring parish of St. Klemens in Dogern.

Waldshut-Tiengen's municipal council consists of 26 unpaid city councillors whose chairperson is the mayor (Oberbürgermeister).

The last municipal election on 13 June 2004 yielded the following division of seats: Previously, a Schultheiß (village head) stood at the lead of the town of Waldshut, including an eight-person council.

The Oberbürgermeister is directly elected by eligible voters for a term of eight years and is head of the municipal council.

From his outfit, the man is taken to be a ranger (German: Waldhüter), and is therefore also deemed to be a "canting" coat of arms, being somewhat suggestive of the former town's name.

The Madonna and Child on the right side come from Tiengen's old town seal, and are also known to date back quite a long way.

This is where the western branch of the North-South Transmission Line – the world's oldest – coming from Herbertingen ends.

For local passenger transport, there is a ferry connection across the river to the Swiss community of Full.

Special buildings in Waldshut are the Schultheißschen Haus, the Greiffenegg-Schlössle, the Waldvogtei (forest reeve's house), the Lower Gate (Unteres Tor) or Basler Tor (west town gate), the Roll'sche Haus and the town hall.

The Catholic town parish Church of St. Mary Ascension (St. Maria Himmelfahrt) was built by Peter Thumb between 1753 and 1755 in the Baroque style.
