Magnolia Hall, also known as the McCrary-Otts House, is a historic Greek Revival mansion in Greensboro, Alabama, United States.

In 1850, William Murphy, a lawyer and legislator, sold a prime lot to David F. McCrary, a prominent cotton broker and planter who had originally come from North Carolina and married Elizabeth Cowan Lowry, daughter of a leading Alabama family.

McCrary had Murphy's house moved and hired the well known architect B.F. Parsons, originally from Massachusetts, to design a mansion, which was completed in 1858.

Inside are large four-over-four rooms, 14-foot ceilings, chandelier medallions, and a grand, mahogany-railed staircase in the spacious hallway.

W. E. Yerby, in his History of Greensboro, concluded that Magnolia Hall "is indisputably one of the finest antebellum mansions in Alabama...[and] a perfect example of late Greek Revival architecture.
