The Grand Ballon (French pronunciation: [ɡʁɑ̃ balɔ̃]) or Great Belchen (German: Großer Belchen [ˌɡʁoːsɐ ˈbɛlçn̩]; Alsatian: Grosser 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.

Grand Ballon means "great [round-topped] mountain" because a ballon in French is a geographical term for a mountain with a rounded summit, similar to the German Kuppe.

Some still call it Ballon de Guebwiller , after the name of the closest town, Guebwiller, located 8 km (5 mi) to the east. It is 1,423.7 metres (4,671 ft) high.

According to the Köppen climate classification, the top of the Grand Ballon features a subalpine climate (Köppen: Dfc) due to its high altitude comparable to the Alps or the Pyrenees.
