New Durham is a town in Strafford County, New Hampshire, United States. The population was 2,638 at the 2010 census. It is drained by the Merrymeeting , Cocheco and Ela rivers, and is known for Merrymeeting Lake. New Durham is home to the Powder Mill Fish Hatchery, located on Merrymeeting Road. Also located here is the Lions Club's Camp Pride, a camp for children and adults with special needs.
Granted by the Masonian Proprietors in 1749 as Cochecho Township, New Durham was settled in 1750 almost entirely by colonists from Durham. It would be incorporated as New Durham on December 7, 1762. With a somewhat uneven and rocky surface, the town was better suited to grazing than cultivation. Lumber became the chief article of trade, and by 1859 New Durham had five sawmills and four shingle mills. It also had two gristmills, and a gunpowder factory called the Eureka Powder Works.
