George A. Caldwell, sometimes known as Big George Caldwell (August 24, 1892 – March 12, 1966), was a Louisiana building contractor and state official. In the 1930s, during the Great Depression, he served as Superintendent for Construction at Louisiana State University, where he was known to "rake off 2 per cent of the cost of all building projects." Caldwell managed the construction of nine buildings on the campus as federal Public Works Administration (PWA) projects in Baton Rouge. These included the university library and the structures housing the dairying and physics departments.
