Dickson Glacier, Glacier in Torres del Paine National Park, Chile

Dickson Glacier is a large expanse of ice located in the southeastern section of the Southern Patagonian Ice Field. The valley below it is accessible through several hiking trails that connect to camping areas and the main circuit route.

Named in 1897 by Swedish explorer Otto Nordenskjöld after Baron Oscar Dickson, patron of his 1895-1896 Patagonia expedition. In 1895 the glacier had a tongue reaching over 4.5 km south from Cerro Cubo, with a southern front calving into Dickson Lake and a northern front joining the Frías glacier. By 1975 it had retreated markedly, leaving a trim line of vegetation along its margins; between 2011 and recent years it thinned 2.5 to 8 m per year.

The glacier and its lake carry the name of Baron Oscar Dickson, the Swedish patron who funded Otto Nordenskjöld's 1895–1896 expedition to Patagonia and Tierra del Fuego; Nordenskjöld named the ice for him in 1897. The Dickson lake at the glacier's southern front is where calving icebergs drop, and the valley is the route hikers follow on the park's northern circuit toward the remote sections.

The glacier's western part lies in Chile's Torres del Paine National Park, its eastern tongue divided with Argentina after the 1998 Fitz Roy–Cerro Daudet boundary agreement. The Argentine sector borders Los Glaciares National Park without belonging to it. Access is from the Chilean side; the ice feeds the Dickson lake, where calving occurs.

The glacier's name was given by Swedish explorer Otto Nordenskjöld in 1897 to honour Baron Oscar Dickson, patron of his 1895-1896 expedition to Patagonia and Tierra del Fuego. The ice flows down to Dickson Lake, where calving icebergs break off from the southern front.
