Jethro Exum Sumner (1733 – c. March 18, 1785) was a North Carolina landowner and businessman, and an officer in the Continental Army during the American Revolutionary War. Born in Virginia, Sumner's military service began in the French and Indian War as a member of the state's Provincial forces. After the conclusion of that conflict, he moved to Bute County, North Carolina, where he acquired a substantial amount of land and operated a tavern. He served as Sheriff of Bute County, but with the coming of the American Revolution, he became a strident Patriot, and was elected to North Carolina's Provincial Congress.
