The Cross and Nelson Hall Historic District encompasses two historic buildings on the campus of Southern Arkansas University in Magnolia, Arkansas. Cross Hall and Nelson Hall were both built in 1936 by the Public Works Administration (PWA) as dormitories for boys and girls, respectively. They are two-story L-shaped brick buildings with Colonial Revival and Collegiate Gothic stylistic elements. Cross Hall has since been converted into classrooms and professors' offices; Nelson Hall now houses student services and the admissions office.
