The Haisla (also Xa’islak’ala, X̄a’islakʼala, X̌àʼislakʼala, X̣aʼislak’ala, Xai:sla) are an indigenous people living at Kitamaat in the North Coast region of the Canadian province of British Columbia. Their indigenous language is named after them in most English usage, though its actual name is X̄a’islak̓ala. The name Haisla is derived from the Haisla word x̣àʼisla or x̣àʼisəla '(those) living at the rivermouth, living downriver'. Along with the neighbouring Wuikinuxv and Heiltsuk people, they were incorrectly known in the past as the Northern Kwakiutl.
