Barton is a town in southwestern Tioga County, New York, United States.

The region was already settled in 1796 when John Shepard bought 1,000 acres (4.0 km2) by the current location of Waverly.

It is reported that the town was named after Belva Ann Lockwood of Royalton, New York (near Lockport), one of the first female lawyers in the country, the first woman to argue a case before the Supreme Court and the first woman to be on an official ballot running for president of the US in 1884 and 1888.

The Southern Tier Expressway (New York State Route 17) passes across the town next to the Susquehanna River.

New York State Route 17C also follows the river, but on the north side.

New York State Route 34 is a north-south highway that intersects NY-17C at Waverly.

27.4% of all households were made up of individuals, and 12.4% had someone living alone who was 65 years of age or older.
