Algonquin is either a distinct Algonquian language closely related to the Ojibwe language or a particularly divergent Ojibwe dialect. It is spoken, alongside French and to some extent English, by the Algonquin First Nations of Quebec and Ontario. As of 2006, there were 2,680 Algonquin speakers, less than 10% of whom were monolingual. Algonquin is the language for which the entire Algonquian language subgroup is named; the similarity among the names often causes considerable confusion. Like many Native American languages, it is strongly verb-based, with most meaning being incorporated into verbs instead of using separate words for prepositions, tense, etc.

The Algonquin people are an Indigenous people who now live in Eastern Canada. They speak the Algonquin language, which is part of the Algonquian language family. Culturally and linguistically, they are closely related to the Odawa, Potawatomi, Ojibwe, Mississaugas, and Nipissing, with whom they form the larger Anicinàpe (Anishinaabeg). Algonquins are known by many names, including Omàmiwinini and Abitibiwinni or the more generalised name of Anicinàpe.
