Seymour Burr (1754/1762–1837) was an African-American slave in the Connecticut Colony in the North American British Colonies and United States. Owned by the brother of Colonel Aaron Burr, who was also named Seymour, he was known only as Seymour (sometimes spelled Seymore) until he escaped and used the surname Burr to enlist in the British Army in the early days of the American Revolution. The British promised the personal freedom of any African-American slave who enlisted or escaped to fight against the Continental Army, and Burr wanted more than anything to be free. However, he was quickly captured and forcibly returned to his owner.
