Heiltsuk , also known as Haí?zaqv, Bella Bella and Haihais, is a dialect of the North Wakashan (Kwakiutlan) language Heiltsuk-Oowekyala that is spoken by the Haihai (Xai'xais) and Bella Bella First Nations peoples of the Central Coast region of the Canadian province of British Columbia, around the communities of Bella Bella and Klemtu, British Columbia. Bella Bella is the headquarters of the Heiltsuk Nation government.
Heiltsuk is spoken in the villages of Bella Bella and Klemtu, both located on coastal islands in British Columbia not far from Bella Coola and Ocean Falls. It is one of the four Northern Wakashan languages, the others being Haisla (spoken in Kitimaat), Oowekyala (in Rivers Inlet), and Kwakwala (in Alert Bay, Port Hardy, and various settlements).
Heiltsuk is considered to be a dialect of Heiltsuk-Oowekyala, which, like neighbouring Haisla and Kwak'wala, are part of the Northern Wakashan language group. Heiltsuk has both conversational and ceremonial forms.
There are mainly three vowel sounds in the Heiltsuk dialect noted as /i, u, a/, although nine other sounds or allophones are heard as [?, ?, ?, ?, ?, ?, æ, ?, ?].
