Döttingen (German: [ˈdœtɪŋən]) is a municipality in the district of Zurzach in the canton of Aargau in Switzerland.

Some items from the Neolithic period and two Roman-era estates have been discovered in Döttingen. The modern municipality of Döttingen is first mentioned in 1239 as Totingen. Until the 19th Century it was also known as Grossdöttingen.

The monastery of Sankt Blasien Abbey in the Black Forest had large estates in Döttingen and possessed a manor house in the village. It was part of the low court of the Klingnau district of the Bishopric of Constance after 1269.

In March 1798, the French Army marched into Switzerland, and proclaimed the Helvetic Republic. Döttingen was a short-lived municipality in the Canton of Baden. During the War of the Second Coalition, the front line between the French and Austrians ran through the middle of the Aare. On 17 August 1799 the Austrian troops tried to cross the Aare at Döttingen. From the mouth of the Surb river, they bombarded the French army on the other side of the river with artillery. The French returned the fire and were able to prevent Austrian crossing. The villages of Kleindöttingen and Eien, on the other side of the river, were completely destroyed and there were several dozen deaths. The biannual Übereschüsset festival commemorates the event.

Until the formation of a separate parish in 1848 it was part of the Klingnau parish. In 1961 the Catholic Church of St. John was built by Hermann Baur.

The local economy was dominated by agriculture and viticulture, until the railway arrived in 1859 (see Döttingen railway station). It developed into a regional industrial center, mostly processing wood. In 1902, in the former hamlet of Beznau a hydroelectric plant was built. In 1948 an oil-fired power plant was built in the municipality. Then, in 1969 and 1971 two blocks of the nuclear power plant NOK were built. In 2000 more than half of the workforce worked in manufacturing.

Since 1950, the largest Wine Festival in German-speaking Switzerland has taken place annually in Döttingen.
