Fort Saint-Jean is a fort in the Canadian province of Quebec located on the Richelieu River. The fort was first built in 1666 by soldiers of the Carignan-Salières Regiment of France who had travelled to New France to assist the young colony. It was part of a series of forts built along the Richelieu River. Over the years, it was destroyed and rebuilt several times, but it is, after Quebec City, the military site that has been occupied non-stop for the longest time in Canada. The fort is designated as a National Historic Site of Canada, and it currently houses the Royal Military College Saint-Jean. The fort has been continually occupied since 1748, and is the core from which the city of Saint-Jean-sur-Richelieu, Quebec grew around. Fort Saint-Jean played a crucial role in the British defense strategy during the 1775 American invasion of the Province of Quebec.

The siege of Fort St. Jean (September 17 – November 3, 1775 French: Siège du Fort Saint-Jean) was conducted by American Brigadier General Richard Montgomery on the town and fort of Saint-Jean, also called St. John, St. Johns, or St. John's, in the British province of Quebec during the American Revolutionary War. The siege lasted from September 17 to November 3, 1775. After several false starts in early September, the Continental Army established a siege around Fort St. Jean. Beset by illness, bad weather, and logistical problems, they established mortar batteries that were able to penetrate into the interior of the fort, but the defenders, who were well-supplied with munitions, but not food and other supplies, persisted in their defence, believing the siege would be broken by forces from Montreal under General Guy Carleton. On October 18, the nearby Fort Chambly fell, and on October 30, an attempt at relief by Carleton was thwarted. When word of this made its way to St. Jean's defenders, combined with a new battery opening fire on the fort, the fort's defenders capitulated, surrendering on November 3. The fall of Fort St. Jean opened the way for the American army to march on Montreal, which fell without battle on November 13. General Carleton escaped from Montreal, and made his way to Quebec City to prepare its defences against an anticipated attack.
