Glassy Mountain is a mountain in the Chattahoochee National Forest in Rabun County, Georgia, with its USGS GNIS summit at 34°50′44″N 83°30′02″W / 34.84556°N 83.50056°W / 34.84556; -83.50056, which is 3,415 feet (1,041 m) AMSL. It is bypassed on its northern flank by a major two-lane highway that carries U.S. Route 76 and Georgia State Route 2 east and west.

It is also the location of NOAA Weather Radio station KXI81, which serves nearby Clayton, Georgia (to the east-northeast), Lake Burton (to the west and southwest), and adjacent areas of northeast Georgia, upstate South Carolina, and western North Carolina. A radio tower and a fire lookout tower are both located atop the mountain.

In 1888, Glassy Mountain was owned by John Ferguson, whose grandfather had built a homestead there before the American Revolutionary War.^[1]
