Sir George Yonge, 5th Baronet, KCB, PC, FRS (/jʌŋ/; 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 was quoted to have often said that he had inherited £80,000 from his father, acquired another £80,000 when he married and £80,000 from Parliament but Honiton had "swallowed it all," This was due to the huge briberies which were commonplace to influence the electorate in rotten borough elections of the time.

Yonge was appointed to the Privy Council of the United Kingdom in 1782, and acted as Governor of the Cape Colony for a short period from 1799 to 1801.

In 1755, he inherited Escot House near Ottery St Mary, Devon, on the death of his father.

[2] Initially he was interred at the place of his death but his remains were later exhumed and transported by sea to be laid to rest in the family crypt in the parish of Colyton.
