The Tagish or Tagish Khwáan are a First Nations people of the Athabaskan-speaking ethnolinguistic group that lived around Tagish Lake and Marsh Lake, in Yukon of Canada. The Tagish intermarried heavily with Tlingit from the coast and the Tagish language became extinct in 2008. Today Tagish people live mainly in Carcross or Whitehorse and are members of the Carcross/Tagish First Nation or the Kwanlin Dün First Nation.
