Marian Cruger Coffin (September 16, 1876 – February 2, 1957) was one of the first American women to work as a professional landscape architect, and became famous for designing numerous gardens for members of the East Coast elite to whom she had connections through her mother's side of the family. As a child, she received almost no formal education but was home-tutored while living with her mother's relatives in upstate New York.
