The Laxgibuu or Laxgyibuu (variously spelled) is the name for the Wolf "clan" (phratry) in the language of the Tsimshian nation of British Columbia, Canada, and southeast Alaska.
The name Laxgibuu derives from gibuu, which means wolf in the Gitxsan and Nisga'a languages.
Other crests used by some matrilineal house-groups of the Laxgibuu include black bear.
Some Laxgibuu house-groups are related to Wolf clan groups among the Tahltan and Tlingit First Nations to the north.
Descendants of some of these migrants share with their distant Tlingit relatives variants on the "Bear Mother" story which has been well recorded by anthropologists and folklorists.
