State Route 100 (SR 100) is a 136.5-mile-long (219.7 km) state highway that travels south-to-north through portions of Meriwether, Troup, Heard, Carroll, Haralson, Polk, Floyd, and Chattooga counties in the northwestern part of the U.S. state of Georgia. The route begins at US 27 Alt./SR 18/SR 41/SR 109 in Greenville and ends at US 27/SR 1/SR 114 in Summerville.

## Route description

SR 100 begins at an intersection with US 27 Alt./SR 18/SR 41/SR 109 in Greenville in Meriwether County. Moving north, SR 100 travels concurrent with SR 54 just east of the interchange with Interstate 85 (I-85) east of Hogansville. Once in Hogansville, SR 100 turns north concurrent with US 29/SR 14 for a short distance before continuing northwest alone. Southeast of Franklin, SR 100 joins US 27/SR 1. Just west of Franklin, SR 100, along with SR 34, splits from US 27 and continues west. In less than 1 mile (1.6 km), SR 100 splits from SR 34 and continues northwest. SR 100 continues north and travels concurrent with SR 5 for a short distance east of the Georgia–Alabama state line before continuing north. As SR 100 moves toward Tallapoosa, it crosses I-20, where it is the first eastbound exit in the state for that highway. Crossing US 78 in Tallapoosa, SR 100 travels concurrent with US 27 south of Cedartown. South of Cedartown, SR 100 turns west following US 278 for a brief distance before resuming a northwestern path. In Cave Spring, SR 100 turns west for a brief distance concurrent with US 411 before turning north once again. SR 100 turns west concurrent with SR 20 for a short distance before resuming its northern course toward Summerville. SR 100 ends at the intersection of US 27/SR 114 in Summerville in Chattooga County.
