Maryville lies in the Foothills of the Great Smoky Mountains. Chilhowee Mountain, the outermost Ridge of the Western Smokies, rises prominently to the south. Chilhowee's eastern flank known locally as "The Three Sisters" is visible from almost anywhere in the city, and dominates the southern horizon along US-321 between Maryville and Walland. Maryville is bordered on the north by Maryville's twin city, Alcoa, Tennessee. A number of small suburbs including Wildwood, Ellejoy, and Clover Hill surround Maryville to the east and west.
