The Old Gulf County Courthouse is an historic redbrick courthouse building located at 222 North 2nd Street in Wewahitchka, Florida. It was built in 1927 in the Classical Revival style after Wewahitchka was designated the county seat of newly created Gulf County. In 1965 the county seat was moved to Port St. Joe and a new courthouse was built there. The old courthouse still functions as an auxiliary to the Port St.
