Raetia (/ˈrʃ(i)ə/ REE-sh(ee-)ə; Latin: [ˈrae̯tɪ.a]; also spelled Rhaetia) was a province of the Roman Empire, named after the Rhaetian (Raeti or Rhaeti) people. It bordered on the west with the country of the Helvetii, on the east with Noricum, on the north with Vindelicia, on the south-west with Transalpine Gaul and on the south with Venetia et Histria, a region of Roman Italy.

The Roman empire in the time of Hadrian (ruled 117-138 AD), showing, on the upper Danube river, the imperial province of Raetia (Switzerland/Tyrol/Germany south of the Danube), with no legions deployed there in 125.
Province of Raetia highlighted.

It thus comprised the districts occupied in modern times by eastern and central Switzerland (containing the Upper Rhine and Lake Constance), southern Germany (Bavaria and most of Baden-Württemberg), Vorarlberg and the greater part of Tyrol in Austria, and part of northern Lombardy in Italy. The region of Vindelicia (today eastern Württemberg and western Bavaria) was annexed to the province at a later date than the others. The northern border of Raetia during the times of Augustus and Tiberius was the River Danube. Later the Limes Germanicus marked the northern boundary, stretching for 166 km north of the Danube. Raetia linked to Italy across the Alps over the Reschen Pass, by the Via Claudia Augusta.

The capital of the province was Augusta Vindelicorum, present-day Augsburg in southern Germany.
