Wangen im Allgäu (Low Alemannic: Wãnge) is a historic city in southeast Baden-Württemberg, Germany.

During the late Middle Ages, the city's growth was amplified by its central location at the crossroads between Ravensburg, Lindau, Leutkirch, and Isny and the growing trade through the Alps.

Wangen's production and export of manufactured goods, particularly scythes and canvas, gave the city a tremendous positive trade balance.

This surplus money was used to acquire lands outside of the city walls, thus giving Wangen a safeguard against economic fluctuations.

In 1973, Wangen was officially designated by the Baden-Württemberg state government to Großen Kreisstadt (large district town) due to its population having reached 20,000.

Despite major fires in 1539, 1793, and 1858, the old part of the town remains a juxtaposition of architectural elements ranging from those of the Early Middle Ages to those of the late Baroque era.

The local history museum, Heimatmuseum in der Eselmühle, was opened in 1974 in a former mill acquired by the city in 1969.

Wangen is serviced by the Schwäbische Zeitung newspaper as well as the local Regio TV television station.
