Lord Charles Greville Montagu (1741 – 3 February 1784) was the last Royal Governor of the Province of South Carolina from 1766 to 1773, with William Bull II serving terms in 1768 and 1769–1771.

His attempts to enforce the 1765 Stamp Act made him unpopular with the local colonials as governor, and led to his departure during the American Revolution.

Charles was captured recruiting soldiers on British prison ships in New York but was released by General Nathanael Greene.

Charles even tried to convince American General William Moultrie to join his regiment, but failed.

Charles and his recruits made up the Duke of Cumberland's army regiment, and the outfit was discharged in 1783.
