The Twana (Skokomish, Toanhooches) lived on the Southeastern side of the Olympic Peninsula in northwestern Washington, on both sides of the Hood Canal. They now live on or near the Skokomish Indian Reservation in Washington. They spoke a Coast Salish language and numbered about one thousand in the 1980s.
