Lax-Kwʼalaams, previously called Port Simpson until 1986, is an Indigenous village community in British Columbia, Canada, not far from the city of Prince Rupert. It is located on Port Simpson Indian Reserve No. 1, which is shared with other residential communities of the Tsimshian Nation. The Nine Allied Tribes are: Gilutsʼaaw, Ginadoiks, Ginaxangiik, Gispaxloʼots, Gitando, Gitlaan, Gitsʼiis, Gitwilgyoots, and Gitzaxłaał.

Fort Simpson was a fur trading post established in 1831 by the Hudson's Bay Company (HBC) near the mouth of the Nass River in present-day British Columbia, Canada. In 1834, it was moved to the Tsimpsean Peninsula, about halfway between the Nass River and the Skeena River, and was later referred to as Port Simpson or as the native name Lax Kw'alaams. The fort was part of the HBC's Columbia Department.
