The Little River is a small river located mostly in Cherokee County, Georgia, and forming the jagged part of the Cherokee/Fulton (formerly Cherokee/Milton) county line, and part of the more recent Milton city limit. It is a tributary of the Etowah River, however their confluence is now submerged beneath Lake Allatoona. It flows generally from east to west, and divides the Woodstock area to the south and Holly Springs area to the north. Its largest tributary is Noonday Creek, a stream which flows northward out of Cobb and through Cherokee, and now also empties directly into the lake.
