Curtis Bay is a residential / commercial / industrial neighborhood in the southern portion of the City of Baltimore, Maryland, United States. The neighborhood is located on steep sloping heights, about four city blocks wide and fifteen blocks long and above and surrounded on three sides in a highly industrialized waterfront area in the southern part of the city, and receives its name from the body of water to the east in which it sits. The cove of "Curtis Bay" with two small branches - Stone House Cove and Cabin Branch is fed from the southwest by Curtis Creek which in turn is formed further south by Marley Creek and Furnace Branch/Creek in Anne Arundel County. Adjoining nearby to the east is Thoms Cove near Hawkins Point at the north end of the Marley Neck peninsula.
