John Carnegie, 1st Earl of Northesk (1611–1667), was a Scottish noble who supported the Royalist cause during the Wars of the Three Kingdoms.

Carnegie was the son of David Carnegie and Eupheme Wemyss, a descendant of Henry Sinclair, 3rd Lord Sinclair, and was younger brother of David Carnegie, 1st Earl of Southesk. He was born before 1611 and lived at Inglismaldie Castle.^[1]

Carnegie had already been created Earl of Ethie and Lord Lour in 1647 but relinquished those titles in exchange for the 1662 creations.^[1] It was under the title Earl of Ethie that he was fined £6,000 under Cromwell's Act of Grace.^[2]

Carnegie died on 8 January 1667.^[1]

He married twice, firstly to Magdalen Haliburton (b. c. 1580–1650), daughter of Sir James Haliburton. Secondly to Margery Maule, daughter of Andrew Maule, on 29 April 1652. With his first wife he had six children:^[1]
