Allatoona is an unincorporated community in Bartow County, in the U.S. state of Georgia. The community is located along Allatoona Creek, 6 miles (9.7 km) southeast of Cartersville. It was once a small mining community until a dam was erected at the base of the Etowah River, completely flooding the town of Allatoona. It is today perhaps best known as the site of the Battle of Allatoona.
