Winchester is a town in Cheshire County, New Hampshire, United States.

The town also includes the village of Ashuelot and part of Pisgah State Park.

Originally named "Arlington" in honor of Charles Fitzroy, Earl of Arlington, this town was one of those established in 1733 by colonial Governor Jonathan Belcher as protection for the Massachusetts Bay Colony border at the Connecticut River.

[3] After being designated a part of the Province of New Hampshire in 1741, the town was granted to Colonel Josiah Willard, commander of the Fort Dummer outpost.

The coming of the Ashuelot Railroad in 1850 fostered the growth of textile mills and wooden-ware factories, especially box manufacture and leather tanning.

The highest point in Winchester is 1,424-foot (434 m) Franklin Mountain, near the town's northeastern corner.

24.3% of all households were made up of individuals, and 9.6% were someone living alone who was 65 years of age or older.

[9] Since 1998, Winchester has held its annual Pickle Festival each September on its Main Street.
