Companies Headquartered in Maryland

Maryland has long been a hub for business. Its proximity to Washington DC makes it attractive for businesses that thrive on government contracts, particularly the defense sector. Maryland’s proximity to the sea—and location midway up the Atlantic shore—makes it a hub for the transporation of goods, or the seagoing vessels that move them.

Our list of companies headquartered in Maryland is drawn from the Fortune 1000, Inc. 5000, and other sources. The result? Nearly 100 Maryland companies that lead a vibrant business community.
