George Carteret, 1st Baron Carteret (July 1667 – 22 September 1695) was son of Sir Philip Carteret (died 1672) and the grandson of George Carteret. His mother was Lady Jemima Montagu, daughter of Edward Montagu, 1st Earl of Sandwich. He was left an orphan at the age of five, and was raised by his paternal grandparents. He married Lady Grace Granville (daughter of John Granville, 1st Earl of Bath and created Countess Granville in 1715), and by her was the father of John Carteret, 2nd Earl Granville.
He was ennobled as Baron Carteret of Hawnes in 1681 in recognition of his grandfather's long career of loyalty to the English Crown, both during the English Civil War and after the Restoration of Charles II. He died in 1695, aged only 26; his widow outlived him by half a century.
