Wissembourg (French pronunciation: [visɑ̃buʁ] ⓘ; South Franconian: Weisseburch [ˈvaɪsəbʊʁç]; German: Weißenburg [ˈvaɪsn̩bʊʁk] ⓘ) is a commune in the Bas-Rhin department in Grand Est in northeastern France.

At the abbey in the late 9th century the monk Otfried composed a gospel harmony, the first substantial work of verse in German.

In 1354 Emperor Charles IV made it one of the grouping of ten towns called the Décapole that survived annexation by France under Louis XIV in 1678 and was extinguished with the French Revolution.

Many early structures were spared: the Maison du Sel (1448), under its Alsatian pitched roof, was the first hospital of the town.

The Maison de Stanislas was the retreat of Stanisław Leszczyński, ex-king of Polish-Lithuanian Commonwealth, from 1719 to 1725, when the formal request arrived on 3 April 1725 asking for the hand of his daughter in marriage to Louis XV.

The Prussians were nominally commanded by the Crown Prince Frederick, but ably directed by his chief of staff, General Leonhard Graf von Blumenthal.

The Geisberg monument commemorates the battle; the town's cemetery holds large numbers of soldiers, including the stately tomb of French general Abel Douay who was killed in combat.
