North Quincy, Illinois is an unincorporated community and neighborhood located within and immediately north of the outskirts of its parent city of Quincy. Parts of North Quincy also extend into the Riverside and Ellington townships of Adams County as a result of urban sprawl. Collectively, North Quincy functions as Quincy's largest suburb, separated from its parent city by Locust Street, a rail line, and woodlands that follow Cedar Creek - the borders are approximate. With few exceptions, much of the layout of the community does not follow the traditional grid street pattern of its parent city.
