Curtis Bay is a residential / commercial / industrial neighborhood in the southern portion of the City of Baltimore, Maryland, United States.

"The Bay", as it is often called colloquially, also offers a variety of housing, townhouses, rowhouses, individual homes, (both constructed of wood-frame, brick, stone and concrete block/stuccoed) and corner stores, taverns/bars.

Curtis Bay is also home since 1897 to the United States Coast Guard Yard (formerly the U.S. Revenue Cutter Service until 1915) on Hawkins Point Road / extending south from Pennington Avenue (Maryland Route 173) on Arundel Cove off Curtis Creek on the border line with neighboring suburban Anne Arundel County to the south.

The former town hall, real estate office, volunteer fire station, and meeting/assembly hall on the second floor for Curtis Bay was constructed on the heights overlooking the new town and rapidly developing industrial waterfront along Fairview Avenue (now Fairhaven Avenue) facing Filbert Street by a successor developing firm, the South Baltimore Harbor and Improvement Company in 1905.
