House at 203 Islington Road

The House at 203 Islington Road is a historic house at 203 Islington Road in Newton, Massachusetts. It is an elaborately decorated Late Victorian house, built in buff-colored stone with dark brick trim elements. Built in 1870, it is the only surviving element of a larger estate (known as "Islington") built by Ezra Winslow; the main estate house, overlooking the nearby Charles River, has long been demolished. It was briefly featured in episode 1 of the 31st season of the PBS television series This Old House (2009).

The house was listed on the National Register of Historic Places in 1986.
