State Road 189 (SR 189) is a north–south highway in the panhandle of Florida. It leads from U.S. Route 98 in downtown Fort Walton Beach to just east of State Road 85 at the Eglin AFB West Gate where its southern section terminates. The northern section begins at an intersection with State Road 4 in Baker, Florida north to the Alabama / Florida state line where Alabama State Route 137 begins upon crossing the Alabama state line. Both segments were once connected through Eglin AFB.
