The Athens Governmental Buildings are a complex of buildings in central Athens, Ohio, United States. Among these buildings are the Athens County Courthouse, the Athens City Hall, and the former post office, now Haning Hall of Ohio University. The current post office is a much more recent building away from the town center, on East Stimson Avenue. The oldest of the buildings included was built in 1804. Together, they were added to the National Register of Historic Places in 1979.
