The Pine Tree Flag was one of the flags used during the American Revolution. The flag, which featured a pine tree with the motto "An Appeal to Heaven," or less frequently "An Appeal to God", was originally used by a squadron of six frigates that were commissioned under George Washington's authority as Commander-in-chief of the Continental Army in October 1775.

Joseph Reed was an American lawyer, military officer, politician, and Founding Father of the United States. He served as aide-de-camp to George Washington, as adjutant general of the Continental Army and fought in several key battles during the American Revolutionary War. He is credited with designing the Pine Tree Flag used during the war.
