Henry John George Herbert, 3rd Earl of Carnarvon, FRS (8 June 1800 – 10 December 1849), styled Lord Porchester from 1811 to 1833, was a British writer,[1] traveller, nobleman, and politician.

[2] He wrote the tragedy Don Pedro, King of Castile which was staged at Drury Lane in 1828 with William Macready and Ellen Kean.

In 1831, Porchester was elected to the House of Commons for Wootton Bassett as a Tory, a seat he held until the following year when the constituency was abolished by the Great Reform Act.

It was during Carnarvon's lifetime that the family seat of Highclere Castle was redesigned and rebuilt by Sir Charles Barry into a Victorian mansion.

Herbert played first-class cricket in 1822 when he was recorded in one match, totalling 1 run with a highest score of 1 and holding 2 catches.
