Germania Superior was an imperial province of the Roman Empire. It comprised an area of today's western Switzerland, the French Jura and Alsace regions, and southwestern Germany. Important cities were Besançon (Vesontio), Strasbourg (Argentoratum), Wiesbaden, and Germania Superior's capital, Mainz (Mogontiacum). It comprised the Middle Rhine, bordering on the Limes Germanicus, and on the Alpine province of Raetia to the south-east. Although it had been occupied militarily since the reign of Augustus, Germania Superior was not made into an official province until c. 85 AD.

Germania, also called Magna Germania, Germania Libera, or Germanic Barbaricum to distinguish it from the Roman province of the same name, was a historical region in north-central Europe during the Roman era, which was associated by Roman authors with the Germanic people. The region stretched roughly from the Middle and Lower Rhine in the west to the Vistula in the east. It also extended at some point as far south as the Upper and Middle Danube and Pannonia, and to the known parts of southern Scandinavia in the north. Archaeologically, these people correspond roughly to the Roman Iron Age of those regions. While dominated by Germanic people, Magna Germania was also inhabited by a few other Indo-European people.
