The Nine Nations of North America is a book written in 1981 by Joel Garreau.
In it, Garreau suggests that North America can be divided into nine regions, or "nations", which have distinctive economic and cultural features. He also argues that conventional national and state borders are largely artificial and irrelevant, and that his "nations" provide a more accurate way of understanding the true nature of North American society. Paul Meartz of Mayville State University called it "a classic text on the current regionalization of North America". The Nations reflected here are included in a Michael F. Flynn short story, in which all the Nine Nations have gained independence.
