Patrick Ferguson, Scottish soldier, designed the Ferguson rifle (died 1780)

Major Patrick Ferguson was a British Army officer who designed the Ferguson rifle. He is best known for his service in the 1780 military campaign of Charles Cornwallis during the American Revolutionary War in the Carolinas, in which he played a great effort in recruiting American Loyalists to serve in his militia against the Patriots.

The Ferguson rifle was one of the first breech-loading rifles to be put into service by the British military. It was designed by Major Patrick Ferguson (1744–1780). It fired a standard British carbine ball of .615" calibre and was used by the British Army in the American Revolutionary War at the Battle of Brandywine in 1777, and possibly at the Siege of Charleston in 1780.
