Mont Sainte-Odile is a 764-metre-high peak in the Vosges Mountains in Alsace in France, immediately west of Barr. The mountain is named after Saint Odile. It has a monastery/convent at its top called the Hohenburg Abbey, and is notable also for its stone fortifications called "the Pagan Wall." In 1992, Air Inter Flight 148 crashed near this area.

The Vosges are a range of medium mountains in Eastern France, near its border with Germany. Together with the Palatine Forest to the north on the German side of the border, they form a single geomorphological unit and low mountain range of around 8,000 km2 (3,100 sq mi) in area. It runs in a north-northeast direction from the Burgundian Gate to the Börrstadt Basin, and forms the western boundary of the Upper Rhine Plain.
