The Petit Ballon (German: Kleiner Belchen) or Little Belchen, is, at 1272m, one of the highest peaks of the Vosges Mountains in the department of Haut-Rhin, Alsace in France, about 5 km away from the village of Wasserbourg. The Rothenbrunnen mountain hut is 500m below. A car park is a further 500m away.

The Col du Petit Ballon pass (elevation 1,163 m (3,816 ft)) is close to the summit.

The mountain is part of the Belchen System, a group of mountains with the name "Belchen" (in German) that may have been part of a Celtic sun calendar.
