Mount Rainier is a mountain 54 miles (87 kilometres) southeast of Seattle, Washington, in the United States. The volcano is the highest mountain in the Cascade Range, at 14,410 feet (4,392 metres). The top of the mountain is mostly covered by snow and glaciers. Rainier is an active volcano, but has not had an eruption for more than 100 years. Some describe Rainier as dormant or inactive.

On March 2, 1899, U.S. President William McKinley made the mountain and area around it Mount Rainier National Park. It was the country's fifth national park.
