Finsterwalder Glacier (67°19′S66°20′W) is a glacier, 2 miles (3 km) wide and 10 miles (16 km) long, flowing southwest from the central plateau of Graham Land, Antarctica, toward the head of Lallemand Fjord. Its mouth lies between the mouths of Haefeli Glacier and Klebelsberg Glacier, the three glaciers merging with Sharp Glacier where the latter enters the fjord.
