George Hamilton (12 March 1812 – 2 August 1883), was a pioneer overlander, artist, settler, and police officer in the Colony of South Australia, serving as Commissioner of Police for fifteen years. Origins Hamilton came from an old Herefordshire family and as a youth was educated at Harrow School before serving as midshipman in the Royal Navy. Farming was his major interest when he emigrated to Australia, firstly to Sydney, before overlanding sheep to Port Phillip, Victoria in March, 1837. He was the first European to settle on the future townsite of Gisborne, Victoria on about 24 March 1837.

During this period he was an activist for the humane treatment of horses, publishing two significant books on that topic, these early endeavours in the prevention of animal cruelty now being recognised at the National Museum of Australia.

Inspector William Searcy was promoted to Hamilton's former position of Chief Inspector.
