Marjory Stoneman Douglas House, Environmental activist residence in Coconut Grove, Miami, United States.

The Marjory Stoneman Douglas House is a wooden residence in the Coconut Grove neighborhood of Miami, built in 1926 with a T-shaped floor plan. The exterior combines timber framing, brick, and stucco, with irregularly placed windows and curved roof shingles.

George Hyde designed the house in 1926 for Marjory Stoneman Douglas, who lived there until her death in 1998. It was during her decades in this home that she wrote the book that changed public understanding of the Everglades.

Douglas called the house "a workshop, more than a house", and it served as a meeting point for South Florida conservationists. Her 1947 book The Everglades: River of Grass described the declining quality of the wetlands while campaigns for a national park were under way. The state bought the property in 1991, calling her one of Florida's most distinguished citizens.

The house sits on Stewart Avenue in Coconut Grove and can be seen from the street. The interior is not open to visitors, so a visit means walking around the outside and taking in the grounds.

The house was bought by the state of Florida in 1991, which described Douglas as "one of Florida's most distinguished citizens." It was named a National Historic Landmark in 2015, seventeen years after her death.
