Gumlog is an unincorporated lakeside community and census-designated place in Franklin County, Georgia, United States.

[4] Gumlog is located in the northeast corner of Franklin County at primary coordinate point 34°30′16.4″N 83°6′16.4″W / 34.504556°N 83.104556°W / 34.504556; -83.104556 (34.504556, -83.104556).

[5] It consists of extensive residential neighborhoods along the shores of Lake Hartwell on the Savannah River.

The northeast border of the CDP is the centerline of the main stem of the lake, which also forms the state line[6] with South Carolina.

[4] Tugaloo State Park occupies a peninsula on Lake Hartwell in the eastern part of the CDP.

It is 10 miles (16 km) long and crosses over the Gumlog Cove branch of Lake Hartwell.

Some say Gumlog is an amateur translation of the Indian name "tsilalu hi", meaning "Sweet-Gum Settlement."

[24] In 1785, the Yazoo land fraud caused the state of Georgia to surrender its claim on what is now Alabama and Mississippi.
