The federally recognized Muckleshoot Indian Tribe is a group that formed post-Treaty, made up of related peoples who shared territory and later a reservation near Auburn.

Since the mid-19th century, their reservation is located in the area of Auburn, Washington, about 15 miles (24 km) northeast of the port of Tacoma and 35 miles (55 km) southeast of Seattle, another major port. They are descendants of the Duwamish peoples whose traditional territory was located along the Green and White rivers, including up to the headwaters in the foothills of the Cascade Mountains, in present-day Washington State. The Muckleshoot ( Lushootseed: bəqəlšuł ) are a Lushootseed-speaking Native American tribe, part of the Coast Salish peoples of the Pacific Northwest.
