George Boscawen, 3rd Viscount Falmouth,[1] PC (6 May 1758 – 11 February 1808), was a British army officer and statesman in the late 18th and early 19th centuries.

He was the chief justice in the Eyre North of Trent from 1789 to 1790, when he was raised to the position of captain of the Honourable Corps of Gentlemen-at-Arms, serving in 1790–1806 and from 1807 until his death in 1808.

They had three children: Falmouth's wife died on 10 August 1793, and upon his own death in 1808, his estate and titles passed to his eldest son.

Named as Lord Falmouth, he is a recurring character in the Poldark novels by Winston Graham, where he is presented as the dominant political figure in Cornwall in his time, due to his unashamed use of patronage and his influence over Parliamentary elections.

However, Falmouth still gives Poldark his political backing, as in his mind, Ross still gave him extra time with his nephew he wouldn't have had had Hugh never been rescued.
