Elm Cottage/Blanding Farm is a historic house at 103 Broad Street in Rehoboth, Massachusetts. The main block of this 2-1/2 story farmhouse was built c. 1800; its rear kitchen ell was added c. 1840. The house was the site of a long-successful local farming operation owned by the Blanding family. One of its early residents was Dr. William Blanding, a physician who also wrote a significant early work on the older houses of Rehoboth. The house was listed on the National Register of Historic Places in 1983.
