The Siege of Fort Pitt took place during June and July 1763 in what is now the city of Pittsburgh, Pennsylvania, United States.
 The siege was a part of Pontiac's War, an effort by Native Americans to remove the British from the Ohio Country and Allegheny Plateau after they refused to honor their promises and treaties to leave voluntarily after the defeat of the French.
 The Native American efforts of diplomacy, and by siege, to remove the British from Fort Pitt ultimately failed.
 This event is best known as an early instance of biological warfare, where the British gave items from a smallpox infirmary as gifts to Native American emissaries with the hope of spreading the deadly disease to nearby tribes.
Pontiac's War (also known as Pontiac's Conspiracy or Pontiac's Rebellion) was launched in 1763 by a loose confederation of elements of Native American tribes, primarily from the Great Lakes region, the Illinois Country, and Ohio Country who were dissatisfied with British postwar policies in the Great Lakes region after the British victory in the French and Indian War (1754–1763).
 Warriors from numerous tribes joined the uprising in an effort to drive British soldiers and settlers out of the region.
 The war is named after the Odawa leader Pontiac, the most prominent of many native leaders in the conflict.
