The Muckleshoot Indian Tribe, also known as the Muckleshoot Tribe, is a federally-recognized tribe located in Auburn, Washington. The tribe governs the Muckleshoot Reservation and is composed of descendants of the Duwamish, Stkamish, Smulkamish, Skopamish, Yilalkoamish, and Upper Puyallup peoples. The Muckleshoot Indian Tribe was formally established in 1936, after the Indian Reorganization Act of 1934, but its origins lie in the creation of the Muckleshoot Reservation in 1874 and the treaties of Medicine Creek (1854) and Point Elliott (1855).
