Baltimore County is the third-most populous county in Maryland. It is part of the Baltimore metropolitan area. Baltimore County partly surrounds but does not include the independent city of Baltimore. It is part of the Northeast megalopolis, which stretches from Northern Virginia in the south to Boston in the north and includes major American population centers, including New York City and Philadelphia.
The name “Baltimore” derives from Cecil Calvert, 2nd Baron Baltimore (1605–1675), proprietor of the colonial-era Province of Maryland, and the town of Baltimore in County Cork, Ireland.
