Kaiseraugst (Swiss German: Chhäiseraugscht) is a municipality in the district of Rheinfelden in the canton of Aargau in Switzerland. Located on the High Rhine, it is part of the Basel metropolitan region and borders Germany and the canton of Basel-Landschaft. It is named after the Ancient Roman city of Augusta Raurica whose ruins are nearby. The prefix Kaiser- ("imperial") refers to the fact that from medieval times the town formed part of the Habsburg territory of Further Austria, as opposed to the neighbouring village of Augst, which was part of the Canton of Basel in the Old Swiss Confederacy.

Founded as a Roman fort, Castrum Rauracense, around AD 300, Kaiseraugst has a rich history tied to its strategic position along the Rhine. Today, it is one of the fastest-growing residential and industrial centers in the region, hosting major companies like Hoffmann-La Roche. The municipality is also known for the abandoned Kaiseraugst Nuclear Power Plant project, which sparked significant environmental protests in the 1970s.
