The Russell Glacier is a medium-sized glacier on the north flank of Mount Rainier, Washington. Named for the geologist Israel Russell, it covers and contains 3.1 billion ft<sup>3</sup> (88 million m<sup>3</sup>) of ice. Starting from its highest point at , the Russell Glacier flows northeast towards the Carbon Glacier and contributes ice to the larger glacier before becoming distinct below . With most of the ice located from to , the glacier only descends to , unlike the much lower extent of the Carbon Glacier. Echo Rock and Observation Rock, two minor sub-peaks of Rainier, lie northwest of this glacier. Meltwater from the glacier eventually reaches the Carbon River.
