Fort Mountain is a mountain in northern Georgia, just east of Chatsworth. It is part of the Cohutta Mountains, a small mountain range at the southern end of the Appalachian Mountains. It also lies within the Chattahoochee National Forest.

Fort Mountain State Park is a 3,712-acre (15.02 km2) Georgia state park located between Chatsworth and Ellijay on Fort Mountain. The state park was founded in 1938 and is named for an ancient 885-foot-long (270 m) rock wall located on the peak. The nomination form for the National Register of Historic Places describes the wall as "more of a marker than a fortification, separating the north peak from the southern end."
