Mactaquac Dam, a hydro-electric power generating facility on the St. John River in New Brunswick, Canada
•
Mactaquac, New Brunswick, unincorporated community in the Fredericton area
It includes those parts of the old Fredericton North district that were west of the Westmorland Street Bridge as well as some suburban communities previously in the district of Mactaquac.
Following the success of preserving historic buildings at Upper Canada Village when the upper St. Lawrence River valley was flooded by the Long Sault Dam, the government of New Brunswick created the King's Landing Historical Settlement to save several buildings which would otherwise have been flooded by the Mactaquac Lake.
