The Mary Marshall Houses is a duplex building in Savannah, Georgia, United States. It is located in the southwestern civic block of Oglethorpe Square and was built in the 1840s^[1] as rental property for Mary Marshall. It is part of the Savannah Historic District.^[1]

A structure on the same lot, but which faced onto East President Street, is visible in Historic American Buildings Survey photographs taken in the mid-20th century. This building was later demolished, after which the rears of today's duplex were extended.^{[citation needed]}

In a survey for the Historic Savannah Foundation, Mary Lane Morrison found the building to be of significant status.^[2] In 1964, Walter C. Hartridge wrote: "This trust lot, which is bounded by Abercorn and Drayton Streets, contains two buildings that are among the finest structures of the Greek Revival period in the United States.^[3] Hartridge also stated, incorrectly, that the property was designed by Charles B. Cluskey, although he could have been responsible for its early form that was later expanded upon.^{[citation needed]}
