Elizabeth Macquarie was the second wife of Lachlan Macquarie, who served as Governor of New South Wales from 1810 to 1821. She played a significant role in the establishment of the colony and is recognised in the naming of many Australian landmarks including Mrs Macquarie's Chair and Elizabeth Street, Hobart. Governor Macquarie named the town of Campbelltown, New South Wales after his wife's maiden name and a statue of her now stands in Mawson Park, Campbelltown.

Major General Lachlan Macquarie, CB was a British Army officer and colonial administrator from Scotland. Macquarie served as the fifth Governor of New South Wales from 1810 to 1821, and had a leading role in the social, economic, and architectural development of the colony. He is considered by historians to have had a crucial influence on the transition of New South Wales from a penal colony to a free settlement and therefore to have played a major role in the shaping of Australian society in the early nineteenth century.
