The Southern Historical Collection is a repository of distinct archival collections at the University of North Carolina at Chapel Hill which document the culture and history of the American South. These collections are made up of unique primary materials, such as manuscripts, letters, photographs, diaries, drawings, scrapbooks, journals, oral histories, maps, ledgers, moving images, literary manuscripts, albums, and other materials.

On January 14, 1930, the Southern Historical Collection was officially established, using the holdings of the North Carolina Historical Society (1844-early 20th century), and material collected by Dr. J. G. de Roulhac Hamilton.
