Major Henry Somerset, 7th Duke of Beaufort, KG (5 February 1792 – 17 November 1853), styled Earl of Glamorgan until 1803 and Marquess of Worcester between 1803 and 1835, was a British peer, soldier, and politician.
Beaufort was commissioned a cornet in the 10th Hussars on 18 June 1811. He was promoted to lieutenant in the 14th Light Dragoons on 21 August, but transferred back to the 10th Hussars on 6 September. Worcester also served as an aide-de-camp to the Duke of Wellington in Portugal and Spain between 1812 and 1814.
In 1813, Beaufort was returned as Member of Parliament (MP) for the Monmouth Boroughs, as a Tory, and continued to hold the seat until 1831. On 26 October 1815, he transferred to the 7th Hussars. In the following year, he was appointed a Lord of the Admiralty under Lord Liverpool, serving on the Board until 1819. On 2 December 1819, he was made a captain in the 37th Foot, and on 30 December, was promoted to the rank of major.
In the contentious election of 1831, Beaufort was defeated by Benjamin Hall at Monmouth Boroughs. While Hall's victory was overturned on petition and Beaufort regained the seat, he again lost to Hall in the 1832 election. He was appointed lieutenant-colonel commandant of the Gloucestershire Yeomanry in 1834. In 1835, he successfully contested West Gloucestershire, but left the House when he succeeded as Duke of Beaufort that November. In 1836, he became High Steward of Bristol and was appointed a Knight of the Garter on 11 April 1842.
