The Battle of Bloody Run took place on July 31, 1763, during Pontiac's War. It happened near what is now Elmwood Cemetery in the Eastside Historic Cemetery District of Detroit, Michigan. At that time, about 250 British soldiers tried to attack Pontiac's camp in secret to end the siege of Fort Detroit.

Pontiac was prepared for the attack, possibly because French settlers warned him. He defeated the British at Parent's Creek, which is 2 miles (3.2 km) east of the fort. However, he did not destroy the British force, which could have weakened British morale and stopped further attacks on Fort Detroit. The creek became known as Bloody Run because it was said to have turned red with the blood of 20 British soldiers who died and 41 who were injured. The British soldiers left the battlefield with all the wounded and all but seven of the dead. Captain James Dalyell, the attack's leader, was among those killed. After learning about Dalyell's death, General Jeffery Amherst promised £200 to anyone who killed Pontiac.

Robert Rogers, a well-known frontiersman, was one of the British officers involved in this battle.
