The Snohomish people are a Lushootseed-speaking Southern Coast Salish people who are indigenous to the Puget Sound region of Washington State. Most Snohomish are enrolled in the Tulalip Tribes of Washington and reside on the reservation or nearby, although others are enrolled in other tribes, and some are members of the non-recognized Snohomish Tribe of Indians. Traditionally, the Snohomish occupied a wide area of land, including the Snohomish River, parts of Whidbey and Camano Islands, and the nearby coastline of Skagit Bay and Puget Sound. They had at least 25 permanent villages throughout their lands, but in 1855, signed the Treaty of Point Elliott and were relocated to the Tulalip Reservation. Although some moved to the reservation, the harsh conditions, lack of land, and oppressive policies of the United States government caused many to leave.

The Tulalip Tribes of Washington, formerly known as the Tulalip Tribes of the Tulalip Reservation, is a federally recognized tribe of Duwamish, Snohomish, Snoqualmie, Skagit, Suiattle, Samish, and Stillaguamish people. They are South and Central Coast Salish peoples of indigenous peoples of the Pacific Northwest Coast. Their tribes are located in the mid-Puget Sound region of Washington.
