The Converse Memorial Library – also known as Converse Memorial Building – is a historically significant building designed by noted American architect H. H. Richardson. From 1885 to 1996, it housed the Malden Public Library, which now occupies a modern building adjacent to it. The former library is located at 36 Salem Street, Malden, Massachusetts. The Converse Memorial Building was the last of Richardson's library designs, and is generally considered among his finest works. It was designated a National Historic Landmark in 1987.
