The Russell Glacier is a medium-sized glacier on the north flank of Mount Rainier, Washington.

Named for the geologist Israel Russell,[2] it covers 1.3 square miles (3.4 km2) and contains 3.1 billion ft3 (88 million m3) of ice.

[1] Starting from its highest point at 9,400 feet (2,900 m), the Russell Glacier flows northeast towards the Carbon Glacier and contributes ice to the larger glacier before becoming distinct below 7,000 feet (2,100 m).

[3] Echo Rock and 8,364 ft (2,549 m) Observation Rock, two minor sub-peaks of Rainier, lie northwest of this glacier.

Meltwater from the glacier eventually reaches the Carbon River.
