Silas Deane House in Wethersfield, Connecticut was the home of Silas Deane, the first diplomat for the United States.
Deane built the house in 1766. The two-story Georgian house is L-shaped with gable roof and two interior chimneys.
In 1959, the house was donated to The National Society of the Colonial Dames of America in Connecticut and in 1963-1965, it was restored. It is now open as part of the Webb-Deane-Stevens Museum and includes original furniture and portraits of Deane and his second wife.
The Webb-Deane-Stevens Museum also owns the adjacent 18th-century Joseph Webb House and the Isaac Stevens House in Old Wethersfield. The museum also operates the nearby Buttolph-Williams House, which is owned by Connecticut Landmarks.
It was declared a National Historic Landmark in 1972.
