The Battle of Bound Brook (April 13, 1777) was a surprise attack by British and Hessian forces against a Continental Army outpost at Bound Brook, New Jersey, during the American Revolutionary War. The British objective of capturing the entire garrison was not met, although prisoners were taken. The U.S. commander, Major General Benjamin Lincoln, left in great haste, abandoning papers and personal effects.

Late on the evening of April 12, 1777, four thousand British and Hessian troops under the command of Lieutenant General Charles Cornwallis marched from the British stronghold of New Brunswick. All but one detachment reached positions surrounding the outpost before the battle began near daybreak the following day. Most of the 500-man garrison escaped during the battle by the unblocked route. U.S. reinforcements arrived in the afternoon, but not before the British plundered the outpost and began the return march to New Brunswick.
