State Route 78 (SR 78) is a backward question mark-shaped state highway in the southeast part of the U.S. state of Georgia. The highway runs 59.6 miles (95.9 km) from Soperton north and northwest to Wrightsville, then turning northeast to Wadley and, finally, east, to its eastern terminus.

SR 78 begins at an intersection with SR 46 in the northeast part of Soperton. It heads south, southwest, and northwest to an intersection with U.S. Route 221 (US 221)/SR 15/SR 56 in downtown Soperton. At this point, SR 15 begins a long concurrency with SR 78 to Wrightsville. Two blocks later, SR 78 has a second intersection with SR 46. North of Soperton, SR 78 has an interchange with Interstate 16 (I-16). South of Adrian, SR 86 crosses SR 78's path. When the route arrives in Adrian, it intersects US 80/SR 26. To the northwest, in Wrightsville, SR 78 intersects SR 57. The two routes have a one-block concurrency to the intersection of US 319/SR 15/SR 31. At this intersection, US 319/SR 78 begin a concurrency to the northeast.
