King Philip's War, sometimes called Metacom's War or Metacom's Rebellion, is an armed conflict between Native American inhabitants of present-day southern New England and English colonists and their Native American allies from 1675–1676.

Colonial historian Francis Jennings estimates that the War had killed nearly 7 of every 8 Native Americans and 6 of every 13 English settlers.

King Philip's War is proportionately one of the bloodiest and costliest in the history of America More than half of New England's ninety towns are assaulted by Native American warriors.

The war is named after the main leader of the Native American side, Metacomet, Metacom, or Pometacom known to the English as "King Philip."
