Kitselas, Kitsalas or Gits'ilaasü are one of the 14 tribes of the Tsimshian nation of British Columbia, in northwestern Canada. The original name Gits'ilaasü means "people of the canyon." The tribe is situated at Kitselas, British Columbia, at the upper end of Kitselas Canyon, which is on the Skeena River. It was once a great trading nexus, just outside and upriver from the city of Terrace. It is the most upriver of the 14 tribes and it borders the territory of the Gitxsan nation.
