What is now Hornell was first settled in 1790 under the name "Upper Canisteo", to distinguish it from the community of Canisteo, then known as "Lower Canisteo". The family of Benjamin Crosby were the first settlers in what is now Hornell. The area was incorporated as a town in 1820, as "Hornellsville." The name comes from early settler George Hornell Jr, who built the first gristmill here.

The village is named after Dr. Jonas Baldwin,[3] who built a dam across the Seneca River to generate energy and a private canal to keep the integrity of the water highway. It incorporated in 1848 as the Village of Baldwinsville. Prior to this, the community was known by a number of other names, including McHarrie's Rifts.

The Town of Cambridge, formerly in Albany County, New York, was transferred to Washington County in 1791, shortly after the United States gained independence in the American Revolutionary War.
