George Rex (29 August 1765 - 3 April 1839) was a British-born entrepreneur who spent most of his adult life in the Cape Colony, South Africa.
He founded the town of Knysna in the Western Cape and played a key role in its development.
Rex filled a number of positions in the Cape Colony – including Marshal of the Vice-admiralty Court, notary public to the Governor and advocate for the Crown – before settling on the farm Melkhoutkraal, in the Knysna district.
George Rex was the alleged first son of King George III.
