The Upsala Glacier is a large valley glacier in Argentina's Los Glaciares National Park. It flows from the Southern Patagonian Ice Field, feeding the nearby Perito Moreno Glacier. The glacier terminus is at Lago Argentino. The Upsala Glacier is well known for its rapid retreat,[1] which many see as evidence for global warming.[2]

The name comes from the old spelling with one p of Uppsala University, which sponsored the first glaciological studies in the area. The University is located in Uppsala, Sweden.[3]

The glacier showed almost continual recession up until 1999. The acceleration in ice motion during the two decades preceding 1999 may have been augmented by the release of backstress when the glacier retreated beyond the islands in Brazo Upsala.[4] Another period of even faster retreat started in 2008.[5]
