Briarcliff Manor /ˈbraɪərklɪf/ is a suburban village in Westchester County, New York, less than 30 miles (48 km) north of New York City. It is on 5.9 square miles (15 km2) of land on the east bank of the Hudson River, geographically shared by the towns of Mount Pleasant and Ossining. Briarcliff Manor includes the communities of Scarborough and Chilmark, and is served by the Scarborough station of the Metro-North Railroad's Hudson Line. A section of the village, including buildings and homes covering 376 acres (152 ha), is part of the Scarborough Historic District and was listed on the National Register of Historic Places in 1984. The village motto is "A Village between Two Rivers", reflecting Briarcliff Manor's location between the Hudson and Pocantico Rivers. Although the Pocantico is the primary boundary between Mount Pleasant and Ossining, since its incorporation the village has spread into Mount Pleasant.
In the precolonial era, the village's area was inhabited by a band of the Wappinger tribes of Native Americans. In the early 19th century, the area was known as Whitson's Corners. Walter William Law moved to the area and purchased lands during the 1890s. Law developed the village, establishing schools, churches, parks and the Briarcliff Lodge. Briarcliff Manor was incorporated as a village in 1902, and celebrated its centennial on November 21, 2002. The village has grown from 331 people when established to 7,867 in the 2010 census.
Briarcliff Manor is primarily residential and its population is relatively wealthy. It has about 180 acres (73 ha) of recreational facilities and parks, all accessible to the public. The village has seven Christian churches for various denominations and two synagogues. The oldest church is Saint Mary's Episcopal Church, built in 1851. Briarcliff Manor has an elected local government, with departments including police, fire, recreation, and public works. It has a low crime rate: a 2012 study found it had the second-lowest in the state. In the New York State Legislature it is split between the New York State Assembly's 95th and 92nd districts, and the New York Senate's 38th and 40th districts. In Congress the village is in New York's 17th District.
