Macon, officially Macon–Bibb County, is a consolidated city-county in Georgia, United States. Situated near the fall line of the Ocmulgee River, it is 85 miles (137 km) southeast of Atlanta and near the state's geographic center—hence its nickname "The Heart of Georgia."

The Ocmulgee River is a western tributary of the Altamaha River, approximately 255 mi (410 km) long, in the U.S. state of Georgia. It is the westernmost major tributary of the Altamaha. It was formerly known by its Hitchiti name of Ocheese Creek, from which the Creek (Muscogee) people derived their name.
