Vindonissa (from a Gaulish toponym in *windo- "white") was a Roman legion camp, vicus and later a bishop's seat at modern Windisch, Switzerland . The remains of the camp are listed as a heritage site of national significance. The city of Brugg hosts a small Roman museum, displaying finds from the legion camp.

Excavations along the western edge of the Roman camp have discovered a few funeral pyre graves dating to the late Bronze Age (c. 1000–800 BC). The first settlement of Vindonissa was a 1st-century BC Helvetii fortified village on the peninsula between the Aare and Reuss rivers. The settlement was protected by an approximately 350 meters (1,150 ft)-long wood and earth wall, with an up to 7 m (23 ft)-deep trench, which stretched across the narrow neck of the peninsula.
