The 1990 Georgia gubernatorial election was held on November 6, 1990. Lieutenant Governor Zell Miller ran for governor after incumbent Joe Frank Harris was term-limited, defeating Andrew Young, Roy Barnes, and Lester Maddox for the Democratic nomination, and defeated Johnny Isakson, a member of the Georgia House of Representatives. As of 2022, this is the last time that Dade, Walker, Whitfield, Murray, Gilmer, Fannin, Floyd, Gordon, Pickens, Dawson, Forsyth, Hall, Barrow, Jackson, Madison, White, Walton, Paulding, Carroll, Coweta, Troup, Spalding, Pike, Harris, Glynn, Camden, Bryan, and Effingham counties voted for the Democratic candidate for governor.
Miller later served in the U.S. Senate from 2000 to 2005, and was succeeded by Isakson, who then served until his 2019 resignation.
