Henry George Reginald Molyneux Herbert, 7th Earl of Carnarvon (January 19, 1924 - September 11, 2001), was Racing Manager to Queen Elizabeth II from 1969, and one of Her Majesty's closest friends.

The Earl of Carnarvon was only son of the 6th Earl of Carnarvon by his first (American-born) wife Anne Wendell. Like his father, Carnarvon (then known as Lord Porchester) fell for an American, Jean Margaret Wallop, even though she was engaged to another man. Jean had aristocratic connections, in that her grandfather Oliver Henry Wallop, 8th Earl of Portsmouth had settled in the western United States and married the daughter of a Kentucky judge. Her brother is the former Senator Malcolm Wallop. The Earl and Countess of Carnarvon were parents of two sons - the 8th Earl of Carnarvon , and the Hon. Harry Herbert - and one daughter Lady Carolyn Warren.
