United States Post Office and Courthouse, former post office and courthouse in Waycross, Georgia, United States

The United States Post Office and Courthouse is a public administration building in Waycross constructed in 1911 and expanded in 1936. The two-story structure with basement displays Renaissance and Romano-Tuscan features including arched windows, while its interior is finished with Georgia marble, terrazzo flooring, and oak woodwork.

The building was designed by architect James Knox Taylor in 1911 and served as a post office and courthouse until 1975. After it ceased operations as a federal facility, it was listed on the National Register of Historic Places in 1980.

The building's name reflects its original dual role serving both postal and legal functions, marking its importance to the community. The classical architectural details such as arched windows and marble finishes convey the formal character that public institutions were meant to project.

The building stands in Waycross, Georgia, and has housed the Southeast Antique Exchange since after 1980; it is a business, not a federal facility, so visits depend on the shop's opening. The 1911 core and 1936 wings give two floors plus a basement of about 21,700 square feet, with the former second-floor courtroom floored in cork tile.

The 1936 expansion by G. W. Stone added the second story and two-story wings at each end, giving the building its present outline. The second-floor courtroom keeps a cork tile floor, unlike the terrazzo and maple hardwood elsewhere. The building stood empty from 1975 until at least 1980, and it now houses the Southeast Antique Exchange.
