The Grand Ballon or Great Belchen is the highest mountain of the Vosges, located 25 kilometres (16 mi) northwest of Mulhouse, France. It is also the highest point of the Grand-Est French region.

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.
