John Granville, 1st Earl of Bath PC (29 August 1628 – 22 August 1701), of Stowe in the parish of Kilkhampton in Cornwall, was an English Royalist soldier and statesman during the Civil War who played a major role in the 1660 Restoration of the Monarchy and was later appointed Lord Lieutenant of Ireland. He was the first in his family to adopt the modernised spelling as Granville of their ancient surname Grenville, which emphasised their supposed ancient 11th-century origin from the Normandy manor of Granville, Manche.
