Grey Glacier is a glacier in the Southern Patagonian Ice Field, just west of the Cordillera del Paine. It flows southward into the lake of the same name.
The Glacier is in the south end of the Southern Patagonia Ice Field. The surface of the lake can be seen when following the big circuit of Paine Mountain Range at John Garner Pass. There is another view of the glacier from the south shore of the lake where the glacier can be seen in the background, with fragments of ice floating close to the shore. It is located to the west side of the Torres del Paine National Park.
