The Savannah River is a major river in the Southeastern United States, forming most of the border between South Carolina and Georgia. Two tributaries of the Savannah, the Tugaloo River and the Chattooga River, form the northernmost part of the state border. The Savannah River drainage basin extends into the southeastern side of the Appalachian Mountains just inside North Carolina, bounded by the Eastern Continental Divide. The river is around 301 miles (484 km) long.^[4] The Savannah was formed by the confluence of the Tugaloo River and the Seneca River. Today this confluence is part of Lake Hartwell. The Tallulah Gorge is located on the Tallulah River, a tributary of the Tugaloo River that forms the northwest branch of the Savannah River.

Two major cities are located along the Savannah River: Savannah and Augusta, Georgia. They were nuclei of early English settlements during the Colonial period of American history.

The Savannah River is tidal at Savannah proper. Downstream from there, the river broadens into an estuary before flowing into the Atlantic Ocean. The area where the river's estuary meets the ocean is known as "Tybee Roads". The Intracoastal Waterway flows through a section of the Savannah River near the city of Savannah.
