Lieutenant-Colonel William Light (27 April 1786 – 6 October 1839) was a British military officer and colonial administrator. He was the first Surveyor-General of the new British Province of South Australia, known for choosing the site of the colony's capital, Adelaide, and for designing the layout of its streets, six city squares, gardens and the figure-eight Adelaide Park Lands, in a plan later sometimes referred to as Light's Vision.
