Cornish, New Hampshire. Cornish is a town in Sullivan County, New Hampshire, United States. The population was 1,616 at the 2020 census. Cornish has four covered bridges. Each August, it is home to the Cornish Fair. The town was granted in 1763 and contained an area once known as Mast Camp, because it was the shipping point for the tall masts floated down the river by English settlers. It was incorporated in 1765 by colonial governor Benning Wentworth and named for Sir Samuel Cornish, a distinguished admiral of the Royal Navy. Since the 1827 partition of Cheshire County, the town has been within Sullivan County. Since the late 19th century, Cornish has been a well-known summer resort for artists and writers. Sculptor Augustus Saint-Gaudens began coming to Cornish in 1885, seeking a studio away from the summer heat of New York City. Artist friends followed him, including painter and illustrator Maxfield Parrish, who designed and built his estate, the Oaks, in the area. The surrounding area became the center of the popular Cornish Art Colony. Cornish was the residence of the reclusive author J. D. Salinger from the 1950s until his death in 2010. Cornish is the site of the longest wooden covered bridge in the United States, and the longest two-span covered bridge in the world. The Cornish-Windsor Covered Bridge spans the Connecticut River and was built in 1866 at an original cost of $9,000. Cornish also has three other covered bridges: the Blow-Me-Down Covered Bridge, Dingleton Hill Covered Bridge, and Kenyon Bridge.

The eastern part of the town is a portion of the approximately 25,000-acre Blue Mountain Forest Association private game preserve, also known locally as Corbin Park, named after its founder, Austin Corbin.
