John Murray Dunmore (1730 - February 25, 1809) was the British colonial governor of New York ([1770]]-1771) and Virginia (1771-1775). From 1771 to 1774, he directed a series of campaigns against the Indians known as Lord Dunmore's War. The main target of these attacks were the Shawnee, and his purpose was in strengthen Virginia's claims in the west, particularly the Ohio Valley.
