Monmouth, Battle of, June 28, 1778, a drawn battle in the American Revolutionary War. British troops under Sir Henry Clinton had evacuated Philadelphia and begun a march to New York City. The Continental Army under George Washington intercepted them between Monmouth Court House and Freehold, New Jersey.

Major General Charles Lee, in command of the Continental vanguard, mismanaged an attack on the British rear. Washington then brought up the rest of his army, rallied Lee's retreating troops, and improvised defensive positions that enabled the patriots to repulse several counterattacks. During the night the British slipped away.

Monmouth was the last major battle in the North. The patriots suffered 360 casualties. British figures are unknown, but included at least 217 dead.
