Waccabuc is a hamlet and lake in the town of Lewisboro, Westchester County, New York. Waccabuc is considered "New York's Secret Suburb" and is home to a "collection of privacy-loving C.E.O.’s and bright stars in other firmaments," according to an Upstart Business Journal article about the tremendous number of notable residents in a hamlet of just a few hundred people. Waccabuc is known by many outside of the town for its Castle Rock.
Before becoming its own hamlet, Waccabuc was originally a vacation retreat established by the Mead family, who are considered one of the First Families of Westchester. The retreat prided itself for having no "tramps, bars, or malaria." A couple of the hamlet's handful of roads, such as "Tarry-a-Bit," are named after the vacation house they originally served. Waccabuc Country Club's main clubhouse sits at the site of one of the original vacation houses.
