The Odawa (also Ottawa or Odaawaa oʊˈdɑːwə), believed to derive from an Anishinaabe word meaning "traders", are an Indigenous American ethnic group who primarily inhabit land in the Eastern Woodlands region, commonly known as the northeastern United States and southeastern Canada. They have long had territory that crosses the current border between the two countries, and they are federally recognized as Native American tribes in the United States and have numerous recognized First Nations bands in Canada. They are one of the Anishinaabeg, related to but distinct from the Ojibwe and Potawatomi peoples.
After migrating from the East Coast in ancient times, they settled on Manitoulin Island, near the northern shores of Lake Huron, and the Bruce Peninsula in the present-day province of Ontario, Canada. They considered this their original homeland. After the 17th century, they also settled along the Ottawa River, and in the present-day states of Michigan and Wisconsin, as well as through the Midwest south of the Great Lakes in what became the United States. In the 21st century, there are approximately 15,000 Odawa living in Ontario, and Michigan and Oklahoma (former Indian Territory, United States).
The Ottawa dialect is part of the Algonquian language family. This large family has numerous smaller tribal groups or "bands," commonly called a "Tribe" in the United States and "First Nation" in Canada. Their language is considered a divergent dialect of Ojibwe, characterized by frequent syncope.
Odawaa (syncoped as Daawaa, is believed to be derived from the Anishinaabe word adaawe, meaning "to trade," or "to buy and sell"); this term is common to the Cree, Algonquin, Nipissing, Innu, Odawa, and Ojibwe. The Potawatomi spelling of Odawa and the English derivative "Ottawa" are also common. The Anishinaabe word for "Those men who trade, or buy and sell" is Wadaawewinini(wag). Fr. Frederic Baraga, a Catholic missionary in Michigan, transliterated this and recorded it in his A Dictionary of the Otchipwe Language as "Watawawininiwok," noting that it meant "men of the bulrushes", associated with the many bulrushes in the Ottawa River.
