Old Government House is an historic building located in Belair National Park, South Australia, and was South Australia's first official vice-regal summer residence of the Governor of South Australia from 1860 to 1880, and was used by governors Richard Graves MacDonnell (1855–62), Dominick Daly (1862-68) and William Jervois (1877–80). It was constructed from local sandstone, with the red-brick for the quoins sourced from the Blackwood brickworks, and a native timber shingle roof. The residence's indoor plunge-pool was reportedly the first in the colony.
