The Cross and Nelson Hall Historic District encompasses two historic buildings on the campus of Southern Arkansas University in Magnolia, Arkansas.

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.
