James Armistead Lafayette (December 10, 1760 – August 9, 1830) was an African American slave who served the Continental Army in the American Revolutionary War as a double agent. He served under the Marquis de Lafayette, reporting on the activities first of Benedict Arnold – after he had gone over to the British – and then Lord Cornwallis during the run-up to the Battle of Yorktown. He also fed false information to them.
