The Duwamish are a Lushootseed-speaking Southern Coast Salish people in western Washington, and the Indigenous people of metropolitan Seattle.
Prior to colonization, the center of Duwamish society was around the Black and Duwamish rivers in Washington. The modern Duwamish primarily descend from two separate groups: the dxʷdəwʔabš, or Duwamish, and the x̌ačuʔabš, a group of peoples whose traditional territory extends around Lake Washington. Although the primary language used by the Duwamish today is English, the Duwamish historically spoke a subdialect of the southern dialect of Lushootseed, a Coast Salish language spoken throughout much of western Washington.
