The Iroquoian languages are a First Nation and Native American language family.

Scholars are finding that what has been called the Laurentian language appears to be more than one dialect or language.

In 1649 the tribes constituting the Huron and Petun confederations were displaced by war parties from Five Nations villages (Mithun 1985). Many of the survivors went on to form the Wyandot tribe. Ethnographic and linguistic field work with the Wyandot (Barbeau 1960) yielded enough documentation to be able to make some characterizations of the Huron and Petun languages.

The languages of the tribes that constituted the Neutral and the Erie confederations were very poorly documented. These groups were called Atiwandaronk meaning 'they who understand the language' by the Huron, and thus are historically grouped with them.

The group known as the Meherrin were neighbors to the Tuscarora and the Nottoway (Binford 1967) and may have spoken an Iroquoian language. There is not enough data to determine this with certainty.

First Nations is a term that collectively refers to various Aboriginal peoples in Canada who are neither Inuit nor Métis. There are currently over 630 recognized First Nations governments or bands spread across Canada, roughly half of which are in the provinces of Ontario and British Columbia. The total population is nearly 700,000 people. Under the Employment Equity Act, First Nations are a "designated group", along with women, visible minorities, and persons with physical or mental disabilities. They are not defined as a visible minority under the Act or by the criteria of Statistics Canada.

The term First Nations (most often used in the plural) has come into general use for the indigenous peoples of the Americas located in what is now Canada, except for the Arctic-situated Inuit, and peoples of mixed European-First Nations ancestry called Métis. The singular, commonly used on culturally politicized reserves, is the term First Nations person (when gender-specific, First Nations man or First Nations woman). A more recent trend is for members of various nations to refer to themselves by their tribal or national identity only, e.g., "I'm Haida," or "We're Kwantlens," in recognition of the distinctiveness of First Nations ethnicities.
