The Gwa'Sala-Nakwaxda'xw Nations are a union of two Kwakwaka'wakw peoples in a band government based on northern Vancouver Island in British Columbia, Canada, whose main reserve community is near the town of Port Hardy in the Queen Charlotte Strait region of the Central Coast region of British Columbia, Canada. The band government is a member of the Kwakiutl District Council and, for treaty negotiation purposes, the Winalagalis Treaty Group which includes three other members of the Kwakiutl District Council (the Quatsino First Nation, the Da'naxda'xw Awaetlatla Nation, and the Tlatlasikwala Nation).

The Gwa'sala-'Nakwaxda'xw Nation was originally two distinct First Nations, the Gwa'sala and the 'Nak'waxda'xw (Nakoaktok). In the mid-1960s the Federal Government relocated the two nations to the current reserve, Tsulquate, and amalgamated them (along with the neighbouring Kwakiutl First Nation) into one group. Eventually the Gwa'sala-'Nakwaxda'xw Nations and the Kwakiutl First Nation separated into the two groups that are recognized by the federal government to this day. Their current main community is at Tsulquate IR No. 4 near Port Hardy.^[1]
