Dr. Joseph Warren (June 11, 1741 – June 17, 1775) is an American doctor who plays a leading role in American Patriot organizations in Boston in early days of the American Revolution, eventually serving as president of the revolutionary Massachusetts Provincial Congress.

Warren enlists Paul Revere and William Dawes on April 18, 1775, to leave Boston and spread the alarm that the British garrison in Boston is setting out to raid the town of Concord and arrest rebel leaders John Hancock and Samuel Adams.

Warren participates in the next day's Battles of Lexington and Concord, which are commonly considered to be the opening engagements of the American Revolutionary War.

Warren had been commissioned a Major General in the colony's militia shortly before the June 17, 1775 Battle of Bunker Hill.

Rather than exercising his rank, Warren serves in the battle as a private soldier, and is killed in combat when British troops storm the redoubt atop Breed's Hill.

His death, immortalized in John Trumbull's painting, The Death of General Warren at the Battle of Bunker's Hill, June 17, 1775, galvanizes the rebel forces, and he has been memorialized in many place names in the United States.
