The Battle of Wyoming (also known as the Wyoming Massacre) was an encounter during the American Revolutionary War between American Patriots and Loyalists accompanied by Iroquois raiders. The clash took place in the Wyoming Valley of Pennsylvania on July 3, 1778, in Exeter and Wyoming, Pennsylvania. More than 300 Patriots were killed in the battle.

After the battle, settlers claimed that the Iroquois raiders had hunted and killed fleeing Patriots, and had then ritually tortured 30 to 40 (who had surrendered) until they died.
