Grahamsville, New York

Downtown Grahamsville

Grahamsville is an unincorporated hamlet at the junction of NY 42 and 55 in the Town of Neversink, in Sullivan County, New York, USA. It is near the western end of Rondout Reservoir, and is the southernmost community in the Catskill Park. It has the ZIP Code 12740 (also applied to the surrounding area) and the 985 telephone exchange in the 845 area code.

Grahamsville has long been known in the area as being a "dry town" as the sale of alcohol is forbidden. There is a bar known as the Hasbrouck House, located just outside the hamlet.

The center of Grahamsville, mainly located along Route 55 and Chestnut Creek west of Route 42, consists of the town hall, post office, fire department, and some other businesses, with an adjoining residential area. To the east of the junction is Tri-Valley Central School and the Grahamsville Historic District, listed on the National Register of Historic Places. It is the largest developed area in the town of Neversink.

The buildings in the historic district reflect the early development of the community. The area was not settled permanently until after the War due to a reputation for brutal raids by the Native American population (the hamlet takes its name from the leader of a Continental Army unit massacred nearby in 1778) and the manorial land ownership system that remained in some areas of the Hudson Valley through the 1840s. The church and homes in the historic district are what grew up around the western end of a stage road (today part of Route 55) to Wawarsing, nearby to the east in Ulster County.
