The Battle of The Cedars (French: Les Cèdres) was a series of military confrontations early in the American Revolutionary War during the Continental Army's invasion of Quebec that had begun in September 1775. The skirmishes, which involved limited combat, occurred in May 1776 at and around The Cedars, 45 km (28 mi) west of Montreal, Quebec. Continental Army units were opposed by a small number of British troops leading a larger force of Indians (primarily Iroquois), and militia.

400 troops commanded by Colonel Timothy Bedel of Bedel's Regiment occupy a strategic position at The Cedars in early April 1776. Lieutenant Isaac Butterfield led an advance force that arrived at The Cedars on April 26 and began construction of a wooden stockade fort, fortifying it with two four-pound cannons. Bedel and the rest of the detachment arrived on May 6.

Brigadier General Benedict Arnold, commanding the American military garrison at Montreal, had placed a detachment of his troops at The Cedars in April 1776, after receiving rumors of British and Indian military preparations to the west of Montreal. The garrison surrendered on May 19 after a confrontation with a combined force of British and Indian troops led by Captain George Forster. American reinforcements on their way to The Cedars were also captured after a brief skirmish on May 20. All of the captives were eventually released after negotiations between Forster and Arnold, who was bringing a sizable force into the area. The terms of the agreement required the Americans to release an equal number of British prisoners. However, the deal was repudiated by Congress, and no British prisoners were freed.

Colonel Timothy Bedel and Lieutenant Isaac Butterfield, leaders of the American force at The Cedars, were court-martialed and cashiered from the Continental Army for their roles in the affair.
