The Gitga'ata (sometimes also spelled Gitga'at or Gitk'a'ata) are one of the 14 tribes of the Tsimshian nation in British Columbia, Canada, and inhabit the village of Hartley Bay, British Columbia, the name of which in the Tsimshian language is Txałgiu. The name Gitga'ata in the Tsimshian language means "people of the cane" (as in, a ceremonial stick). The Gitga'ata, along with the Kitasoo Tsimshians at Klemtu, B.C., are often classed as "Southern Tsimshian," their traditional language being the southern dialect of the Tsimshian language. Most Tsimshian-speakers in Hartley Bay today, however, speak the form of the language shared by villages to the north. Their band government is the Hartley Bay Indian Band, aka the Gitga'at First Nation.
In 1947, Edmund Patalas ("belonging to the Kitamat tribe at Hartley Bay") described to the Tsimshian ethnologist William Beynon the origins of the Laxsgiik (Eagle clan) people of the "Gitxon" group who migrated from the land of the Haida people on Haida Gwaii first to Kitamaat and then to the Gitga'ata people, where a branch of this group, the House of Sinaxeet, is now considered "the royal Eagle house of Kitkata" (described in Barbeau's Totem Poles).
