The Old Tavern Farm is a historic farmstead at 817 Colrain Road in Greenfield, Massachusetts. The main structure exemplifies the organic growth of a farm complex from colonial days into the 19th century. The main block of the house is a Federal style 2-1/2 story center chimney structure, built c. 1820. A 42-foot (13 m) wing added onto the main block's west side is built in part on a foundation dating to 1740; this section of the house was apparently built in 1794, tearing down the earlier 1740 construction. This wing is attached at its other end to a 19th-century barn.
