The Wilson Glacier is a medium-sized tributary glacier located on the southeast flank of Mount Rainier in Washington.

Named after A.D. Wilson, who was part of an early ascent of Mount Rainier,[3] the body of ice has an area of 0.5 square miles (1.3 km2) and has a volume of 1.9 billion feet3 (54 million m3).

[2] The glacier directly feeds ice to the adjacent, but much larger Nisqually Glacier.

Starting from the head at 9,700 feet (3,000 m), the glacier flows downhill southward.

[4] Meltwater from the glacier feeds the Nisqually River.
