The Otemma Glacier (French: Glacier d'Otemma) is a 7.7 km (4.8 mi) long glacier (2005) situated in the Pennine Alps in the canton of Valais in Switzerland.

In 1973 it had a length of 8.7 km (5.4 mi), and an area of 17.5 km2 (6.8 sq mi)[1] but, like most other alpine glaciers, is known to be receding.

By 2010 it had receded a further 1.2 km (0.75 mi) from its 1973 position.

[2] In summer 2018, the snout zone (terminus) of the glacier collapsed.
