Stratham is a town in Rockingham County, New Hampshire, United States. It is bounded on the west by the Squamscott River. The town is the home of the only U.S. Lindt & Sprüngli factory and the headquarters of the Timberland Corporation. Stratham Hill Park and nearby Gordon Barker Town Forest offer a combined trail system for hikers and mountain bikers. Stratham is home to the Cooperative Middle School, 100 Academic Way and Stratham Memorial School, 39 Gifford Farm Road. High school students from Stratham attend Exeter High School.
Stratham was settled in 1631 and incorporated in 1716. The area, called Winnicutt by the Pennacook Indians, was known as Squamscott Patent or Point of Rocks because of its location between Great Bay and the Squamscott River. Each summer the town hosts the Stratham Fair, held at Stratham Hill Park.
