Chappaqua ( CHAP-ə-kwah) is a hamlet and census-designated place in the town of New Castle, in northern Westchester County, New York. It is on 0.45 square miles (1.2 km2) of land on the east bank of the Hudson River, about 30 miles (50 km) north of New York City. The hamlet is served by the Chappaqua station of the Metro-North Railroad's Harlem Line. In the New York State Legislature it is within the New York State Assembly's 93rd district and the New York Senate's 40th district. In Congress the village is in New York's 17th District.
Chappaqua was founded by a group of Quakers in the 1730s and was the home of Horace Greeley, New-York Tribune editor and U.S. congressman. Since the late 1990s, former President Bill Clinton and former Secretary of State Hillary Clinton have lived there.
In the early 1730s a group of Quakers moved north from Purchase, New York, to settle in present-day Chappaqua. They built their homes on Quaker Road (more recently, Quaker Street) and held their meetings at the home of Abel Weeks. Their meeting house was built in 1753 and still holds weekly meetings each Sunday.
