Albert County (2021 population 30,749) is New Brunswick's third-youngest county, located on the Western side of the Petitcodiac River on the Chignecto Bay in the Bay of Fundy; the shire town is Hopewell Cape. The county was established in 1845 from parts of Westmorland County and Saint John County, and named after Prince Albert. Since the abolition of county municipal governments in 1967, its best-known use is as a census division.
