Preston Hall, or Prestonhall, is a late-18th-century mansion in Midlothian, to the south of Edinburgh, Scotland. It is located north of Pathhead on the east side of the Tyne Water, opposite Oxenfoord Castle on the west side. The house, together with several estate buildings, are the work of architect Robert Mitchell (fl. 1770–1809), and are protected as Category A listed buildings, the highest level of protection for a historic building in Scotland.
