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. It is considered analogous or identical to identically named clans among the neighboring Gitksan and Nisga'a nations.
The name Laxgibuu derives from gibuu, which means wolf in the Gitxsan and Nisga'a languages. In Tsimshian the word is gibaaw (gyibaaw or gyibaw), but Tsimshians still use the word Laxgibuu for Wolf clan.
The chief crest of the Laxgibuu is the Wolf. 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. In the case of the Tlingit, the connection is through Tlingit Wolves who migrated south from what is now Alaska to escape inter-clan warfare and settled among the Tsimshian, Gitxsan, and Nisga'a. 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. The Kitsumkalum Laxgibuu are one example of a Tsimshian Wolf group who own the right to tell this story.
Some Nisga'a Laxgibuu Wilp (House groups) include:
