State Route 75 (SR 75) is a state highway that runs south-to-north through portions of White and Towns counties in northern Georgia. The route runs from its southern terminus at US 129 and SR 11 in Cleveland to its northern terminus at the North Carolina state line and NC SR 175 north of Hiawassee.

The route initially runs north from its southern terminus in Cleveland in White County to its intersection with SR 17, and is co-signed with SR 17 through Helen all the way north into Hiawassee, very near its northern terminus.

SR 77 is also briefly co-signed with US 76 through Hiawassee. Near Helen, the route is known locally as the Helen Highway south of Helen and the Unicoi Turnpike north of Helen.
