The Elm Bank Reservation is a state park and recreation area in Wellesley, Massachusetts. It is also historic for its landscape.

The Elm Bank Reservation got its name in 1740 when Colonel John Jones owned the site and planted elms along Charles River?s banks. The property transferred ownership through time and was even owned at one point by Benjamin Pierce Cheney, founder of American Express. Its famous landscaping was developed in the early 1900s when Cheney?s daughter, Alice, and her husband, Dr. William Hewson Baltzell, built a neo-Georgian manor at the site and employed the Olmstead Brothers to design the gardens of the site. The site is now a US Historic District and is listed on the National Register of Historic Places.
