Lieutenant-General George Boscawen (1 December 1712 – 3 May 1775) was a British Army officer and politician, the fourth son of Hugh Boscawen, 1st Viscount Falmouth.
Believed to have been educated at Eton College, he was commissioned as an Ensign in the First Foot Guards in 1728, and promoted to Captain in 1738. He saw active service during the War of the Austrian Succession, distinguishing himself at the battles of Fontenoy and Dettingen.
On 3 February 1743, he was married to Ann Trevor, the daughter of John Morley Trevor. The couple would go on to have two sons and two daughters. Shortly after his marriage, on 22 February, he was elected as Member of Parliament for Penryn, following the decision of Edward Vernon (who had been simultaneously elected for three different constituencies) to take up his seat at Ipswich. He was promoted to the rank of Colonel on 18 August 1749, and appointed as Aide-de-camp to King George II on 14 October the same year. In 1750 he was made Lieutenant-Governor of the Scilly Isles, a post he would occupy until his death.
On 4 March 1752 he was named colonel of the 29th Regiment of Foot and led that regiment during a lenghy posting to Ireland. He was promoted to the rank of Major general on 14 January 1758, and to Lieutenant general on 22 February 1760. On 16 January 1761, he was transferred to become colonel of the 23rd Regiment of Foot.
