The Algonquin people are an Indigenous people who now live in Eastern Canada and parts of the United States. 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 (including Oji-Cree), Mississaugas, and Nipissing, with whom they form the larger Anicinàpe (Anishinaabeg) group. Algonquins are known by many names, including Omàmiwinini (plural: Omàmiwininiwak, "downstream man/men") and Abitibiwinni (pl.: Abitibiwinnik "men [living] halfway across the water") or the more generalised name of Anicinàpe.
Though known by several names in the past, such as Algoumequin, the most common term "Algonquin" has been suggested to derive from the Maliseet word elakómkwik (IPA: [ɛlæˈɡomoɡwik]): "they are our relatives/allies." The much larger heterogeneous group of Algonquian-speaking peoples, who, according to Brian Conwell, stretch from Virginia to the Rocky Mountains and north to Hudson Bay, was named after the tribe.
