The Terwilliger–Smith Farm is located on Cherrytown Road near the hamlet of Kerhonkson in the Town of Rochester in Ulster County, New York, United States. It was established in the mid-19th century. It has remained on the same lot for its entire existence. With the newest of the farm buildings dating to the early 20th century, it is a rare example of a complete historic farmstead in the county, reflecting different eras in the evolution of local agriculture. It was listed on the National Register of Historic Places in 2002.
