Fort Calgary was a North-West Mounted Police outpost at the confluence of the Bow and Elbow rivers in present-day Calgary, Alberta, Canada. Originally named Fort Brisebois, after the outpost's first commander, the outpost was renamed Fort Calgary in June 1876. The outpost was built in 1875 as a part of the North-West Mounted Police (NWMP) larger effort to curtail American rum and whisky runners in the region, and to establish relationships with the Indigenous peoples of the territory.
