Windisch is a municipality in the district of Brugg in the canton of Aargau in Switzerland .

Windisch is situated at the site of the Roman legion camp Vindonissa . Originally a Celtic God, the name Vindos points to a widespread prehistorical cult of Vindos and the most likely origin of the Windisch place name. In 1064 the current municipality was mentioned as Vinse, and in 1175 as Vindisse. Until the 19th Century the official name was Windisch und Oberburg.

Windisch grew into a regional power following the foundation of Königsfelden Abbey in 1309 in memory of the regicide of King Albert I of Germany in the previous year.
