Deerfield is a town in Rockingham County, New Hampshire, United States. The population was 4,855 at the 2020 census,[2] up from 4,280 in 2010. Deerfield is the location of the annual Deerfield Fair.
Deerfield was originally part of Nottingham. In 1756, residents petitioned for organization of a separate parish, but were denied. In 1765, while a second petition was pending, two local hunters presented colonial governor Benning Wentworth with a deer. Permission was granted, and "Deerfield" was incorporated in 1766. The incorporation act for Deerfield was signed by three members of the Leavitt family, including Capt. Samuel Leavitt who later was one of the town's first selectmen. Leavitts Hill in Deerfield was named for the family, who had first settled in nearby Exeter.[3]
"Deerfield Parade", a hilltop district first settled circa 1740, was located on the early postal route between Concord and Portsmouth. Here, the militia of the Revolutionary and Civil wars trained and "paraded" on the village common. The "Parade" was then a professional, cultural and trade center. About 1798, citizens founded Deerfield Academy, a high school. It burned in 1842.
Once a thriving farm community which was disappointed when bypassed by railroads, the town in 1876 established the Deerfield Fair. Now billed as "New England's Oldest Family Fair", the four-day event draws huge crowds each autumn to admire animals, produce and crafts, or to enjoy amusement park rides.

Portions of the Pawtuckaway Mountains occupy the eastern border of the town. Deerfield is primarily drained by the Lamprey River and its tributary the North Branch River, within the Piscataqua River (Coastal) watershed, while the western edge and northernmost section of town is in the Merrimack River watershed.[4]
