The Corbassière Glacier (French: Glacier de Corbassière) is a valley glacier in the Grand Combin massif in the Pennine Alps in southwestern Valais . It is 9.8 km (6.1 mi) long with an average width of slightly more than 1 km (0.62 mi) and covers an area of 17.4 km2 (6.7 sq mi).

The origin of Corbassière Glacier is on the northern slope of the Grand Combin at over 4,000 m (13,000 ft) above sea level. The glacier tongue currently ends at around 2,300 m (7,500 ft) above sea level.

On the right side of the lower section of the glacier, the Cabane François-Xavier Bagnoud ([kaban fʁɑ̃swa ɡzavje baɲu]; 2645 m above sea level) belonging to the Swiss Alpine Club is a starting point for ascents and glacier tours in the Grand Combin massif.
