Nancy was an American sailing vessel, noted in sources as either a brig or a brigantine, that was chartered to transport war supplies during the American Revolutionary War. After learning that independence had been declared, her captain, according to his daughter, raised the first American flag in a foreign port. Evading British capture, she was later intentionally destroyed with a huge blast on June 29, 1776, during the Battle of Turtle Gut Inlet near Cape May, New Jersey.
