Granted by Massachusetts in 1737, it was first permanently settled in 1749. The town suffered several attacks during the French and Indian War. Nevertheless, by 1759, there were fifty families settled. Incorporated upon January 17, 1760, by Governor Benning Wentworth, it was named after Lieutenant Peter Prescott (1709–1784) of Concord, Massachusetts, a prominent land speculator.

The Contoocook River and Nubanusit Brook offered numerous sites for watermills, and Peterborough became a prosperous mill town. In 1810, the first cotton factory was established. By 1859, when the population was 2,222, there were four new cotton factories, plus a woolen mill. Other industries included two paper mills, an iron foundry, a robot shop, a carriage factory, a basket manufacturer, a maker of trusses and supporters, a boot and shoe factory, seven sawmills, and three gristmills.
