George Clifford III (7 January 1685, Amsterdam – 10 April 1760, Heemstede) was a wealthy Dutch banker and one of the directors of the Dutch East India Company.
He is known for his keen interest in plants and gardens.
Many specimens from Clifford's garden were also studied by Linnaeus for his Species Plantarum (1753).
His grandfather, Englishman George Clifford I, moved from Stow (where his father was rector) to Amsterdam around 1640, beginning an Anglo-Dutch banking dynasty.
Subsequent members of the Clifford Family were prominent leaders in Amsterdam.
