The Old Government House is a heritage-listed former "country" residence used by ten early governors of New South Wales between 1800 and 1847, located in Parramatta Park in Parramatta, New South Wales, in the greater metropolitan area of Western Sydney, New South Wales, Australia. It is considered a property of national and international significance as an archaeological resource. It also serves to demonstrate how the British Empire expanded and Australian society has evolved since 1788.

The governor of New South Wales is the representative of the monarch, King Charles III, in the state of New South Wales. In an analogous way to the governor-general of Australia at the national level, the governors of the Australian states perform constitutional and ceremonial functions at the state level. The governor is appointed by the monarch on the advice of the premier of New South Wales, and serves in office for an unfixed period of time—known as serving At His Majesty's pleasure—though five years is the general standard of office term. The current governor is retired judge Margaret Beazley, who succeeded David Hurley on 2 May 2019.
