Sir George Yonge, 5th Baronet, KCB, PC (17 July 1731 – 25 September 1812), of Escot House in the parish of Talaton in Devon, England, was a British Secretary at War (1782–1783 and 1783–1794). He succeeded to his father's baronetcy in 1755, which became extinct when he died without children. He is remembered by, among other things, the name of Yonge Street, a principal road in what is now Toronto, Canada, so named in 1793 by the Lieutenant-Governor of Upper Canada, John Graves Simcoe.
