The Fairbanks House in Dedham, Massachusetts is a historic house built ca. 1637, making it the oldest surviving timber-frame house in North America that has been verified by dendrochronology testing. Puritan settler Jonathan Fairbanks constructed the farmhouse for his wife Grace (née Smith) and their family. The house was occupied and then passed down through eight generations of the family until the early 20th century. Over several centuries the original portion was expanded as architectural styles changed and the family grew.

The house was built in several stages; the center portion of the present house is the oldest, with a gable-roofed portion at the center. It was once a lobby-entry, hall-parlor house of two stories with a center chimney bay. The oldest section of the house was completed by at least 1641, based on the dendrochronology of several beams in the house. The summer beam was dated to 1637, and other wall boards and beams were dated to 1638, 1640 and 1641.

Today the Fairbanks house is owned and operated by the Fairbanks Family in America, a member-based non-profit organization, as a historic house museum. The Family Association has preserved, studied and interpreted their ancestral home and its collections for over 110 years. The house was declared a National Historic Landmark in 1961, and is listed on the National Register of Historic Places.
