Deerfield is a rural town in Rockingham County known for hosting the Deerfield Fair, one of New Hampshire's oldest agricultural fairs, each autumn. The town's rolling farmland and forested hills have remained largely undeveloped compared to faster-growing communities nearby.

The Deerfield Fairgrounds anchor much of the town's civic identity, while the surrounding countryside offers hiking, hunting, and horseback riding. Deerfield has no significant commercial center, with most shopping trips made to Raymond or Epping.

Housing in Deerfield consists mostly of larger rural lots, drawing families and residents who want agricultural character and open space within a reasonable drive of southern New Hampshire's job centers. The town's strong fair tradition reflects its continued agricultural identity.
