The Flint River is a 344-mile-long (554 km) river in the U.S. state of Georgia. The river drains 8,460 square miles (21,900 km²) of western Georgia, flowing south from the upper Piedmont region south of Atlanta to the wetlands of the Gulf Coastal Plain in the southwestern corner of the state. Along with the Apalachicola and the Chattahoochee rivers, it forms part of the ACF basin. In its upper course through the red hills of the Piedmont, it is considered especially scenic, flowing unimpeded for over 200 miles (320 km). Historically, it was also called the Thronateeska River.

The Flint River rises in west central Georgia in the city of East Point in southern Fulton County on the southern outskirts of the Atlanta metropolitan area as ground seepage. The exact start can be traced to the field located between Plant Street, Willingham Drive, Elm Street, and Vesta Avenue. It travels under the runways of the Hartsfield-Jackson Atlanta International Airport. Flowing generally south through rural western Georgia, the river passes through Sprewell Bluff State Park, approximately 10 miles (16 km) west of Thomaston. Farther south, it comes within 5 miles (8 km) of Andersonville, the site of the Andersonville prison during the Civil War.

In southwestern Georgia, the river flows through downtown Albany, the largest city on the river. At Bainbridge it joins Lake Seminole, formed at its confluence with the Chattahoochee River upstream from the Jim Woodruff Dam, very near the Florida state line. From this confluence, the Apalachicola River flows south from the reservoir through Florida to the Gulf of Mexico.
