Sackville

Town in southeastern New Brunswick, Canada, at the head of the Bay of Fundy's Chignecto Bay, 39 km/24 mi southeast of Moncton, near the Nova Scotia border; population (1991) 5,500. It has varied light industries and is the home of Mount Allison University (1839).

The surrounding Tantramar Marshes were dyked for farming by 17th-century Acadian settlers. Sackville was a shipbuilding centre in the 19th-century. Fort Beauséjour, to the east, was built by the French in 1751 and fell to the British in 1755. It is now a National Historic Site.
