State Route 61 (SR 61) is a state highway that runs south-to-north through portions of Carroll, Douglas, Paulding, Bartow, Gordon, and Murray counties in western and northwestern Georgia. The route runs from its southern terminus at SR 166 north of Carrollton to its northern terminus at SR 33 at the Tennessee state line near Tennga.

The route initially runs northeast from its southern terminus near Carrollton in Carroll County, very briefly touches the northwestern corner of Douglas County, and continues on in the direction of Dallas in Paulding County. From Dallas, the route runs north into Cartersville in Bartow County.

From just north of Cartersville, SR 61 is co-signed with US 411, and parallels I-75 until reaching its northern terminus, after crossing I-75 soon after departing Cartersville on its way to Fairmount and Ranger in Gordon County. SR 61 continues north through Chatsworth in Murray County until it reaches the Tennessee state line and its northern terminus.
