The South Newport River is a 42.6-mile-long (68.6 km)[1] river on the Atlantic coastal plain in the U.S. state of Georgia.

It rises in Long County 3 miles (5 km) south of Walthourville and flows east-southeast, becoming the boundary between Liberty and McIntosh counties.

It flows into Sapelo Sound, an arm of the Atlantic Ocean, south of St. Catherines Island.

[2][3] The river's name most likely is a transfer from Newport, Rhode Island.
