 New York State Route 273 (NY 273) was a state highway in northern Washington County, New York, in the United States. It began at an intersection with U.S. Route 4 (US 4) east of the village of Whitehall and ended at the Vermont state line in the town of Hampton, just east of a junction with NY 22A. The route passed through largely rural areas and entered only one community, the small hamlet of East Whitehall.
