Gitlaxt'aamiks /ɡɪtˈlɑːdəmɪks/ or New Aiyansh /aɪˈænʃ/ is a Nisga'a village about 100 km north of Terrace, in the heart of the Nass River valley, Canada. It is one of four Nisga'a villages. Though it is located in British Columbia, it is also considered the "capital of the Nisga'a Nation." The Nisga'a Lisims Government building (Wilp si'Ayuukhl Nisga'a), which opened in 2000, is located here. The area is home to 806 people and the Nisga'a Memorial Lava Beds Provincial Park. Gitlaxt'aamiks is located overlooking a lava flow that erupted in the 18th century.
