The Arolla Glacier (French: Glacier d'Arolla) is a 4 km (2.5 mi) long glacier (2005) situated in the Pennine Alps in the canton of Valais in Switzerland. In 1973, it had an area of 13.17 km2 (5.08 sq mi).

The Glacier d'Arolla is in fact composed of two glaciers: the Glacier du Mont Collon and the Haut Glacier d'Arolla.

The Glacier du Mont Collon has a length of almost 5 km and a width of about 1 km at the top. It covers an area of 7 km2 (2.7 sq mi). It begins on the tips of Oren (3525 m) and flows north through a corridor bordered by the Little Mount Collon (3,556 m) and Bishop (3716 m) west, and Mont Collon in the east.
