Joseph Martin, Jr. (1740–1808) was a brigadier general in the Virginia militia during the American Revolutionary War, in which Martin's frontier diplomacy with the Cherokee people is credited with not only averting Indian attacks on the Scotch-Irish American and English American settlers who helped win the battles of Kings Mountain and Cowpens, but with also helping to keep the Indians' position neutral and from siding with the British troops during those crucial battles. Historians agree that the settlers' success at these two battles signaled the turning of the tide of the Revolutionary War—in favor of the Americans.

The Battle of Kings Mountain was a military engagement between Patriot and Loyalist militias in South Carolina during the Southern Campaign of the American Revolutionary War, resulting in a decisive victory for the Patriots. The battle took place on October 7, 1780, 9 miles (14 km) south of the present-day town of Kings Mountain, North Carolina. In what is now rural Cherokee County, South Carolina, the Patriot militia defeated the Loyalist militia commanded by British Major Patrick Ferguson of the 71st Foot. The battle has been described as "the war's largest all-American fight".
