Gitxsan are an Indigenous people in Canada whose home territory comprises most of the area known as the Skeena Country in English. Gitksan territory encompasses approximately 35,000 km2 (14,000 sq mi) of land, from the basin of the upper Skeena River from about Legate Creek to the Skeena's headwaters and its surrounding tributaries. Part of the Tsimshianic language group, their culture is considered to be part of the civilization of the Indigenous peoples of the Pacific Northwest Coast, although their territory lies in the Interior rather than on the Coast. They were at one time also known as the Interior Tsimshian, a term which also included the Nisga'a, the Gitxsan's neighbours to the north. Their neighbours to the west are the Tsimshian while to the east the Wetʼsuwetʼen, an Athapaskan people, with whom they have a long and deep relationship and shared political and cultural community.
