Fort Jacques-Cartier, Military fort in Cap-Santé, Canada.

Fort Jacques-Cartier is a French fort built after the 1759 Battle of the Plains of Abraham on land conceded around 1703 to Adrien Pichet, on a promontory along the Saint Lawrence at present-day Cap-Santé. Jean-Daniel Dumas had it built with 150 land troops and 450 Troupes de la Marine. Some vestiges remain visible.

Built after the Battle of the Plains of Abraham and the British capture of Quebec in 1759, the fort was ordered by Jean-Daniel Dumas, who deployed 150 regular troops and 450 Troupes de la Marine. It blocked a British advance toward Trois-Rivières, served as winter quarters and a supply depot for the planned spring 1760 counter-attack at Sainte-Foy, and was the only French fort built during the Seven Years' War.

The fort's site lies in what is now the village of Cap-Santé, on land conceded around 1703 to Adrien Pichet, who died in 1739 and had built a house beside the Chemin du Roy on a promontory along the river; the house was later enlarged. The fort marked the southern boundary of the British-occupied zone, where Canadian militiamen of each parish had to hand over their weapons, swear neutrality and loyalty to the King of England, and obtain a passport to travel legally.

The fort site lies in the present-day village of Cap-Santé, on a promontory along the Saint Lawrence River near the Rivière Jacques-Cartier. The ground is uneven where vestiges of the fort remain visible, so sturdy shoes help when walking the site.

Fort Jacques-Cartier was the only French fort built during the Seven Years' War, raised by Jean-Daniel Dumas with 150 regular troops and 450 Troupes de la Marine. It served as winter quarters and a supply depot for the French army preparing the spring 1760 counter-attack that led to the Battle of Sainte-Foy. Some vestiges remain visible in Cap-Santé.
