The Double Glacier (English Double Glacier for "double glacier") is located in Lake Clark National Park in southwest Alaska .

The approximately 300 km² large glacier area is located north of Mount Redoubt in the Chigmit Mountains , a mountain range of the northern Aleutian chain . The highest point of the mountain range is the 2078  m high Double Peak . The glacier area consists of two larger glaciers flowing eastwards as well as several smaller outlet glaciers. The more northerly of the two main glaciers forms the Big River glacier tongue , while the southern one forms the Drift River glacier tongue . On a 4.7 km long stretch, the two glaciers run parallel to the east, separated by a central moraine , before they separate again. The 26 km long northern glacier ends at a glacial rim lake that is drained by the South Fork Big River and Big River . The 19 km long southern glacier turns south in the lower area and feeds the Drift River, which runs south . Both glacier-fed rivers flow into the Cook Inlet .

In the north of the glacier area there is a 1475  m high nunatak . This forms a remnant of the extinct Double Glacier volcano , which has a diameter of about 3.5 km.
