The Trift Glacier (German: Triftgletscher) is a 5 km (3 mi) long glacier (2005) in the Uri Alps near Gadmen, in the extreme east of the canton of Bern in Switzerland.

Overall it covered an area of 16.55 km2 (6.39 sq mi) including glacier sides.

The valley in which lake Triftsee is today used to be filled by a large mass of ice well into the 20th century.

In the 1990s smaller meltwater pools began to form at the glacier tongue and gradually increased in size.

At an altitude of 2520 meters above sea level is the Trifthutte, a mountain hut of the Schweizer Alpen-Club (SAC) that was only accessible via the glacier tongue.
